SECOND EDIT
It seems that upon loading the page, not when submitting, that the two entries (blank rows) are added to my database. I’m really struggling to find my problem here but I have a feeling it’s a fairly stupid error.

I’m having an issue with my php/mysql code posting extra blank rows along with what it’s supposed to post. The code for the validation of the data from my form an for the transmission of the info to the database is below. Every time I enter data in my form and submit it it works fine, however it adds extra rows to the tblLocation, the tblWhere works fine. Can anyone lead me in the right direction here? Let me know if you need more of my code.

CODE IS AS FOLLOWS

if (isset($_POST['butSubmit'])) {

// set variables to data from form    
$user= mysql_real_escape_string($_POST["txtUser"]);
$fName= mysql_real_escape_string($_POST["txtFname"]);
$lName= mysql_real_escape_string($_POST["txtLname"]);
$email= mysql_real_escape_string($_POST["txtEmail"]);
$date= date(DATE_RFC822);
$street= mysql_real_escape_string($_POST["txtStreet"]);
$city= mysql_real_escape_string($_POST["txtCity"]);
$state= mysql_real_escape_string($_POST["lstStates"]);
$zip= mysql_real_escape_string($_POST["txtZip"]);

    //handle html characters
$user = htmlentities($user, ENT_QUOTES);
$fName = htmlentities($fName, ENT_QUOTES);
$lName = htmlentities($lName, ENT_QUOTES);
$email = htmlentities($email, ENT_QUOTES);
$date = htmlentities($date, ENT_QUOTES);
$street = htmlentities($street, ENT_QUOTES);
$city = htmlentities($city, ENT_QUOTES);
$state = htmlentities($state, ENT_QUOTES);
$zip = htmlentities($zip, ENT_QUOTES);
$errorMsg=array();


// initiate testing procedures for form contents 
if($user==""){
    $errorMsg[]="Please enter your Username";
} else {
    $valid = verifyAlphaNum ($user); /* test for non-valid  data */
    if (!$valid){ 
        $error_msg[]="Username must contain only letters (A-Z), numbers (0-9), spaces, dashes(-), and apostrophes (').";
    }
}

if($fName==""){
    $errorMsg[]="Please enter your First Name";
} else {
    $valid = verifyAlphaNum ($fName); /* test for non-valid  data */
    if (!$valid){ 
        $error_msg[]="First Name must contain only letters (A-Z), numbers (0-9), spaces, dashes(-), and apostrophes (').";
    }
}

    if($lName==""){
    $errorMsg[]="Please enter your Last Name";
} else {
    $valid = verifyAlphaNum ($lName); /* test for non-valid  data */
    if (!$valid){ 
        $error_msg[]="Last Name must contain only letters (A-Z), numbers (0-9), spaces, dashes(-), and apostrophes (').";
    }
}

if($email==""){
    $errorMsg[]="Please enter your Email Address";
} elseif (!verifyEmail($email)){
    $errorMsg[]="Correct eMail format is ( example@anysite.com )";
}

    if($street==""){
    $errorMsg[]="Please enter your Street Address";
} else {
    $valid = verifyAlphaNum ($street); /* test for non-valid  data */
    if (!$valid){ 
        $error_msg[]="Street Address must contain only letters (A-Z), numbers (0-9), spaces, dashes(-), and apostrophes (').";
    }
}

    if($city==""){
    $errorMsg[]="Please enter a City";
} else {
    $valid = verifyAlphaNum ($city); /* test for non-valid  data */
    if (!$valid){ 
        $error_msg[]="City must contain only letters (A-Z), numbers (0-9), spaces, dashes(-), and apostrophes (').";
    }
}

    if($state==""){
    $errorMsg[]="Please choose a State";
} else {
    $valid = verifyAlphaNum ($state); /* test for non-valid  data */
    }
}

    if($errorMsg){
    echo "<ul>\n";
    foreach($errorMsg as $err){
        echo "<li style='color: #ff6666'>" . $err . "</li>\n";
    }
    echo "</ul>\n";
} else { 

                 mysql_query("INSERT INTO tblWhere (pk_Username, fldFirstName, fldLastName, fldAdminLevel, fldTotalPosts, fldDateJoined, fldEmail) VALUES ('$user', '$fName', '$lName', '4', '0', '$date', '$email')");
                                if (mysql_errno()) {
                            echo $sql . "<br/>\n" . mysql_error();
                                }

                    mysql_query("INSERT INTO tblLocation (fk_Username, fldStreet, fldCity, fldState, fldZip) VALUES ('$user', '$street', '$city', '$state', '$zip')");
                                if (mysql_errno()) {
                            echo $sql . "<br/>\n" . mysql_error();
                                }
}
mysql_close();
print $user;

EDIT
Here is the full code, maybe this will help?

Your code runs the mysql query outside of the POST check, the mysql query runs no matter what because $errorMsg is not being returned.

Move your mysql logic inside the if (isset($_POST['butSubmit'])) { part of your code.

<?php

include ("validation_functions.php");

date_default_timezone_set('UTC');

$dbh=mysql_connect('webdb.uvm.edu','swakita','password');

  }

mysql_select_db('SWAKITA', $dbh);



if (isset($_POST['butSubmit'])) {

    //handle html characters
$user = htmlentities($user, ENT_QUOTES);
$fName = htmlentities($fName, ENT_QUOTES);
$lName = htmlentities($lName, ENT_QUOTES);
$email = htmlentities($email, ENT_QUOTES);
$date = htmlentities($date, ENT_QUOTES);
$street = htmlentities($street, ENT_QUOTES);
$city = htmlentities($city, ENT_QUOTES);
$state = htmlentities($state, ENT_QUOTES);
$zip = htmlentities($zip, ENT_QUOTES);
$errorMsg=array();

// set variables to data from form    
$user= mysql_real_escape_string($_POST["txtUser"]);
$fName= mysql_real_escape_string($_POST["txtFname"]);
$lName= mysql_real_escape_string($_POST["txtLname"]);
