Hey Deds, I was really pleased to see how you got that to work!
Bye the way, to gain insight into how ad_form and the form template engine works, place something like this at the top of your .tcl page.
ns_log notice it's my page!
set mypage [ns_getform]
if {[string equal "" $mypage]} {
ns_log notice no form was submitted on my page
} else {
ns_log notice the following form was submitted on my page
ns_set print $mypage
}
This print will all the crazy things POSTed to your page into your server log.
