Can't get simple Javascript to work 1

[Maldini]

Hi,
I'm trying to do some simple form validation on an ASP page, but after trying for a couple of hours, it still doens't work.

This is the javascript function I have. When I pass a form as the checkForm variable, I do get alert boxes coming up, but they say 'undefined' instead of what I have.

<Script language="Javascript">

function Validate(checkForm) {

if (checkForm.Username.Value == "") {
alert('No User Name!');
return false;
} else {
alert(checkForm.UserName.Value);
}
return true;
}
</Script>

This is the HTML form; its wrapped in a number of divisions from CSS.

<FORM NAME="UserForm" Method="Post" Action="test.asp">
UserName:
<INPUT TYPE="text" Name="UserName"><BR>

<INPUT TYPE="button" Name="Add" Value="Add" onClick="Validate(document.UserForm)">
</FORM>

Any tips would be greatly appreciated; this problem has driven me mad; since its supposed to be so simple!

Thanks.

The main issue is that "Value" should have a lowercase "v" - JavaScript is case-sensitive.

You might also want to switch "document.UserForm" for "document.forms['UserForm']" and "checkForm.Username" for "checkForm.elements['Username']"

Hope this helps,
Dan

Thanks, solved the problem. It really was the capitalization of 'V' that caused the prob.
