You say forms, so I assume you mean web forms, right? if so...

You could use redirects. see perldoc CGI. it goes something like:

use strict;
use warnings; # i've upgraded to 5.6 last night ;)
use CGI;

my $answer = new CGI;

if ( $date eq "today" ) {
   print $answer->redirect(-uri=>'http://some.server/cgi/script.pl?dat
+e=today');
} else {
   print $answer->redirect(-uri=>'http://some.server/cgi/script.pl?dat
+e=dateItIs');
}

just be sure not to print out the CGI header before doing that - which is my classic blunder when using redirects.

Update:as pointed out above by swiftone and below by Mark Dominus, you probably have form data from the first form you want to pass on to the next. I was trying to keep my example short and sweet so i skipped an example of plugging all that stuff in and settled for just putting one argument for each. But swiftone wisely points to URI::Escape as a great way to format and then feed in a complete adress + arguments to another script you may call on. Basically, don't forget to pass on all the data you've collected on the first screen somehow.
