The following is the code for webhitsdirect's pop under campaign. It currently pops on every page view. I was wondering if somebody could write something that would make this pop every 24 hours instead of every page view. (Sorry if this is the wrong forum)

Here is the code:
<!--Begin WHD Code-->
<script language="javascript">whdAffiliate=128</script>
<script language="javascript" src="">
<!--End WHD Code-->
