ive been reusing my javascript codes before & there seems to be no problem

but now, i have to use client side validation if there is any value on my textbox named emailadd within a form named form1. here is my jscript code:

<SCRIPT LANGUAGE="JavaScript">
<!--
function checkUsername()
{
if (document.form1.emailadd.value.length == 0)
{
alert('Enter your email address');
document.form1.emailadd.focus()
return false;
}
form1.submit()
}
//-->
</SCRIPT>

then on my html code:
<input type="submit" name="Submit" value="Submit" onClick="javascript:checkUsername">

THEN THIS ERROR APPEARS:
document.form1.emailadd.value is null or not an object

can somebody help me?
