Please help with form

Hi there I want this form to do client side validation by checking that the user has entered at least 1 character in each of my fields on the form. The problem is it does not seem to work and jumps through to the asp page and reports an error of 'customers.Password' cannot be a zero-length string. I know this as my database is set for this. But the form should check the fields first before posting to the asp page or am i missing something.

plz be gentle as I am new to this and thank you

<html>
<TABLE WIDTH="600" CELLPADDING="10" CELLSPACING="0" ALIGN="CENTER"
Background="1.jpg" BORDER="2">
<TR>
<TD><BR>
<CENTER>
<script language = "VBScript">

option explicit
private sub chkformdata()
dim tempfirst, templast
dim temppass, tempcity, temppost, temphone
dim tempmail

tempfirst= signup.firstname.value
templast = signup.lastname.value
tempmail = signup.e-mail.value
temppass = signup.password.value
tempcity = signup.city.value
temppost = signup.postcode.value
temphone = signup.homephone.value

if len(tempfirst) = 0 then
msgbox("Sorry you have not entered a valid first name. It

must be at least 1 character long ")
else
if len(templast) = 0 then
msgbox("Sorry you have not entered a valid Last

Name.It must be at least 1 character long ")
else
if len(tempmail) = 0 then
msgbox("Sorry you have not entered a valid E-mail

address.It must be at least 1 character long ")

Your sub must be a function and the function should return false if submitting is not allowed.
And change the input to:
<input type="submit" value="Submit" align="center" onClick = "return chkformdata()">

That should do the trick...

I have done a similar one using ASP.Just have the data entered by the user stored in some variable like this
<%
firstname=Request.Form("firstname")
lastname=Request.Form("lastname")
......

if firstname="" then
%>
<script language="JavaScript">
alert("Firstname not entered")
</script>
<%
response.end
end if
%>

This will check whether the user has entered some values or skipped it.If the user has not entered any value the program will terminate.The program will be executed one and only if all the conditions given by you are satisfied.

Hope you got some idea.
