Thanks for the quick reply - the code seems very advanced and im finding it hard to understand it e.g i have no clue what runat="server" means :-( ... and the problem is i need to explain it when im presenting my website.
At the moment i am only able to check that data has been entered into the field
[HTML]<script type="text/javascript">
<!--
function validate(regfor m) {
//Perform validation checks
//Check that telephone number exsit in this field
if (regform.telno. value=="") {
alert("Please complete the field: Contact number");
regform.telno.f ocus();
return false;
}
return true;
}
//-->
</script>
<form method="get" name="regform" action="regcomp lete.asp" onsubmit="retur n validate(this); ">
Contact Number:<input type="text" name="telno" size="15" />
<input type="submit" value="submit">
</form>[/HTML]
