Loop through the elements of the form and add the value of any field whose
name begins with "Reg_". You may also want to put in some validation that
all the fields are numeric and do not contain any non-numeric characters.
function sumValues() {
var TheSum = 0;
for( var i=0; i<document.FormName.elements.length; i++) {
if( document.FormName.elements[i].name.search(/^Reg_/) != -1
) {
// put numeric validation here?
TheSum += document.FormName.elements[i].value;
}
}
}
