In IE 7 the zip code search form on my page reacts differently when someone clicks submit vs pressing enter. It works correctly when sumbmit is clicked and incorrectly when enter is pressed.

<form name="zip" action="<?php bloginfo('url'); ?>" method="get">
<input type="text" id="zipper" name="locations" size="5" maxlength="5" class="junk-input" onsubmit="return checkForm()" />
<input type="submit" value="" name="schedule" src="/wp-content/uploads/remove-my-junk.png" align="center" class="junk-button" style="background: #f67a3e url(/wp-content/uploads/remove-my-junk.png); border: none; width: 201px; height: 45px;"/>
</form>
The correct result for a zip search of 85718 looks like this: http://getridofit.com/l/85718/?schedule
but pressing enter produces a result like this: http://getridofit.com/l/85718/
Because the button wasnt clicked in order to submit the form. If you dont click the button then the input for
@name[schedule]isnt sent. However if that button input has focus when enter is pressed i think it will send it along properly… You might jsut want to makeschedulea hidden input.
