Page Reload Question

I have a perl/cgi script that includes dynamically created
checkboxes and file names. When a given checkbox is checked I move the
related file. how do I redisplay the page without the checkbox and
file name. In other words, I want to reload the page just as if the
user has entered for the 1st time.

i've tried variations of:

<form action="/cgi-bin/page.cgi" method="post" onsubmit="doRefresh()">

function doRefresh(){
location.replace("/cgi-bin/page.cgi");
//location.reload("/cgi-bin/page.cgi");
//location.reload("");
}
