I am attempting to use javascript to STOP my form from submission when 
BOTH input text boxes are empty.  I get the error message indicated in 
the javascript, but IT DOES NOT STOP MY FORM from being submitted.

I do not have a standard submit button on this form, I have about 10 
different buttons to choose from, the run subroutine and then send you to 
another page.

Code:

Javascript:
<script language="javascript">
<!--
function validate() {
var blnValid = true;
mEmpId=document.Form1.txtEmployeeId.value;
mChkNo=document.Form1.txtCheckAdviceNumber.value;
if (mEmpId == ''  &&  mChkNo == '')
	{blnValid =  false;
	alert("Boolean Value =  " + blnValid);
	
	}
	else
	{blnValid = true;}
	return blnValid
	}
//-->
		</script>

+++++++++++++++++++++++++++++++++++++++++++

and the only code currently in my HTML to call this is:

<form id="Form1" method="post" runat="server" onsubmit="validate();">

Any suggestions would be greatly appreciated.  I was unable to get the 
custom validator to kick in, I would happy to take suggestions on that 
one as well.  

Thanks in advance,

Carole

try returning your validate() routine like below:
<form id="Form1" method="post" runat="server" onsubmit="return validate();">

instead of just
<form id="Form1" method="post" runat="server" onsubmit="validate();">
