problem is all 3 functions display forms and i want them to display one after the other not in the same page. So first i want to display a page showing only s_page then i want to display a page showing ethier l_page or r_page depending on what you input. how is this done. The page keeps reseting making a if statment difficult i have tried using a "lexicon value but it doesnt seem to be working. Keeps displaying the first screen over and over again.

#!/usr/bin/perl
use strict;
use warnings;
BEGIN{my $donce = 0; sub incr{ $donce++;} sub getdo{return $donce}}
use LWP::Simple;
use CGI qw/:standard/;
print "Content-type: text/html\n\n";
had();
#lets me know if user has selected a option yet
if(getdo() == 0)
{s_page(); incr();print getdo();}
else
{
if(param("option") eq  'login')
  {      l_page();    }
else
  {      r_page();     }
}
foot();
