the next button is the same as prev button
$firstrec is the first record in a user group
$lastrec is the last record in a user group
when I reach the $lastrec I want to stop the next button from working and when i reach $firstrec i want the prev button to stop working.

hmmm.. what is the value of the image currently being displayed? Is $id a visitor id or the current image id? assuming $id, $firstrec, & $lastrec are numerical codes representing current image, first image, and last image, and your image codes are sorted numerically.. maybe you're looking for something like this? if ( $id < $lastrec ){ print $q->start_form(-name=>'displaynext',-method=>'POST',-action=>' +next.cgi'); print "<input type=hidden name=i value='$id'>"; print "<input type=hidden name=u value='$username'>"; print $q->submit(-name=>'next',-value=>'next'); print $q->end_form(); } if ( $id > $firstrec ){ print $q->start_form(-name=>'display prev',-method=>'POST',-action=> +'prev.cgi'); print "<input type=hidden name=i value='$id'>"; print "<input type=hidden name=u value='$username'>"; print $q->submit(-name=>'prev',-value=>'prev'); print $q->end_form(); } [download] cheers, J	[reply] [d/l]

if ( $id < $lastrec ){
  print $q->start_form(-name=>'displaynext',-method=>'POST',-action=>'
+next.cgi'); 
  print "<input type=hidden name=i value='$id'>";
  print "<input type=hidden name=u value='$username'>";
  print $q->submit(-name=>'next',-value=>'next');

  print $q->end_form();
}
if ( $id > $firstrec ){
  print $q->start_form(-name=>'display prev',-method=>'POST',-action=>
+'prev.cgi');
  print "<input type=hidden name=i value='$id'>";
  print "<input type=hidden name=u value='$username'>";
  print $q->submit(-name=>'prev',-value=>'prev');
  print $q->end_form();
