I have an asp page that has a form to collect user data in a form.
when the user clicks submit the input is validated. If any fields are
not acceptable the user clicks on a button to go back to the original
form to correct the input. This all works fine until I try to
incorporate a javascript to display a popup calendar which posts the
selected date back to a field on the form. This script works fine in
itself, however if the page is submitted after this script has run and
other fields are not valid, then when I go back to the form ALL the
data entered is cleared. I am fairly new to asp and at a lost as to
what i am doing wrong.
I would appreciate any pointers as to how I can correct this.
My asp page is is follows:
Handles database connects
' contains the Javascript to
handle the popup window
<% If (0 = Request.ServerVariables("CONTENT_LENGTH")) Then %>

End Sub
If Request.Form("Action") = "Submit" Then 'user has submitted
'validate
If pass then
'Process values
Else 'if failed
showForm
End If
Else 'user has NOT submitted
showform
End If

By the way, you should never refer to the request collection without
qualifying which one you are dealing with - Request.Form or
Request.QueryString. You are forcing a search of each collection in turn
until the correct one is found.

Hi Mike
Thanks for the reply.
I have taken your points on board and redesigned the page. It all works
well with the exception of Checkboxes. I have tried searhing here but
cannot seem to find a way to make the the form redisplay and show the
checked state of the checkbox.
In my original form I have the following:
when the form is posted I can get the value of the checkbox using:
strC1 = request.form("C1") which returns "ON" as expected.
however I cannot find a way to set the value back to the posted form.
I would be grateful of any assistance.
Regards
Tony
