<?php if($_POST[reset]) {
unset($_SESSION[display]); } ?>

when i do it this way it resets the counter on the first click then display on the second... is there a way to do it with one click?

If a variable has been unset with unset(), it will no longer be set. isset() will return FALSE if testing a variable that has been set to NULL. Also note that a NULL byte ("\0") is not equivalent to the PHP NULL constant.

If multiple parameters are supplied then isset() will return TRUE only if all of the parameters are set. Evaluation goes from left to right and stops as soon as an unset variable is encountered.
