I keep getting this error saying that it cannot find my javascript function checkpw(). It’s being called by onfocus. 

<script type="text/javascript" >

function checkpw() { 

alert ("working");

}



</script>
</head>
<body>

<h2>Welcome to our webpage.</h2>

<p>{{ reginfo}}</p>
<form action="/validate/" method ="get" >
<p>Username</p>
<input type="text" name="username"  class="textbox"> </input > </br>
<p>Password</p>
<input class="textbox" name="password" id="password" type="text"> </input > </br>
<p>Confirm Password</p>
<input class="textbox" id="checkpw" type="text" onfocus="checkpw()"> </input > </br>
<p>Email<p>
<input class="textbox" name="email" type="text"> </input > </br>

<input type="submit" class="button" value="Submit"> 



</form>

</body>

I’m probably making a really stupid mistake but i’m new to javascript so anything that helps would be great. thanks.

    change: function checkpw() to: function checkPw()
    and: focus="checkpw()" to: focus="checkPw()"

    Edit:
    It is not a reserved word; however the name is already polluted in the global namespace. As Domenic and jimr pointed out, the id attribute is using the same name, thus causing a conflicting condition.

    The solution is still to change either:
    (1) the id value of the input element
    -or-
    (2) the function name (as I stated above)
