Calculate on report details page

[mdav20]

I'm trying to calculate the number of hrs on a report details page.  Its simply (hrs_removed - hrs_installed) nothing fancy.

 

Here is the code I'm trying to use in the footer of my report details page.

 

<SCRIPT LANGUAGE="JavaScript">

 function calculate()
 {
var v_field1 = parseFloat(document.getElementById ("EditRecordhrs_removed").value);
if (isNaN(v_field1)) v_field1 = 0;
var v_field2 = parseFloat(document.getElementById ("EditRecordhrs_installed").value);
if (isNaN(v_field2)) v_field2 = 0;
var v_total = (v_field1 - v_field2);
document.getElementById("EditRecordhrs_total").value = (v_total);
}

document.getElementById("caspioform").onchange=calculate;

</SCRIPT>

Trying to get it populate the hrs_total field after putting in the hrs_removed and hrs_installed and before submitting the form.
