Okay I have a couple of select boxes. When the user clicks on the first select box the form is submitted to itself and I retrieve the value of the selection and make my "select" box into a plain textbox with the value that the user selected. Now my second select box is filtered based on the selection of the first select box. This works great. My problem is that I do more of this later in the form and every time I submit the form to itself my first select box changes values. How can I make the value a constant number?
example of what I have is
<?php
$ckSubmit=$HTTP_POST_VARS['ckSubmit']+1;//Here I am declaring variables that occur after the form has been posted
$industry=$HTTP_POST_VARS['selectIndustry'];
$ind=get_ind_string($industry);
$prarea=$HTTP_POST_VARS['selectPrArea'];
$prarea1 = get_prarea_string($prarea);
if ($ckSubmit>4){
$doSubmit='poreport2.php';}
elseif ($ckSubmit<4){
$doSubmit=$_SERVER['PHP_SELF'];}
?>
