validation problem
hey i want to perform the following code which loops through a number of textboxes(the number of which depends on what number the user enters on the previous page i.e. request.form("members")) and validates each textbox to ensure there is information in them. when i enter a number in the javascript instead of strnum the code works perfectly. but i keep getting an error when i try to assign the value to a variable which is the number entered on the previous page.
does anyone have any suggestions??? <form name="form2" method="post" action="CreateCommittee.asp" onSubmit= "return checkval()"> <% Dim strnum strnum = request.form("members") %> <script> function checkval(){ for (i = 1; i <=<%=strnum;%> i++) { if (eval("document.form2." + 'txtCommitteeMember' + i + ".value.length") == 0){ alert('You must enter a Member.'); return false; } if (eval("document.form2." + 'txtMemberName' + i + ".value.length") == 0){ alert('You must enter a Member Name.'); return false; } } } </script>

I think that u cannot use <%%> inside JScript that 1.
2 is that in VB script u cannot put ; as u did at <=<%=strnum ; %>. 3 you can try put hidden in to the form: <input type=hidden name=memVal value=<%=strnum%>> and then: for (i = 1; i <=document.frm.memVal.value; i++)
