Can someone tell me what is wrong with this statement?
function subtotal(){
var ttot = 1;
for (var i = 1; i < 7; i++){
if(isPosInt(document.forms[0].total(i).value)){
ttot += document.forms[0].total(i).value;
}
document.forms[0].subtot.value = format(ttot);
}
}
I know the "isPosInt" function works because it works for other things and
Mike wrote it...so I did not add it.
And I do have a global varible elsewhere var e =
document.forms[0].elements, but I also can't get "if(isPosInt(ea['total' + i].value))" to work
Will this help? Watch for word-wrap.

Obviously you should remove the values for all "total" fields.
