Milks:
If you really want to do it as you said and JavaScript is not an option
you can do this.
1. Place your form in a template that is cfincluded into the original
template.
2. CFParam all the form variables like so
<cfparam name="form.Firstname" default="">
and in all your form elements in the value field set the
value="#form.FirstName#"
For select boxes, radio buttons and such you'll have to do a bit more
conditional logic but essentially the same concept.
3. When the form is posted on the template it is posted to do your
validation and if you find invalid input somewhere just display the error
message and then cfinclude the template with the form in it again. Because
all your form elements have value="#form.whatever#" in them already they'll
be populated with the data that was just entered.
Hope that helps.
