Another issue...there is a third function called subtotal that adds all the
line totals. subtotal does not work at all.
Ok, I have developed a debug function that puts up a popup window
which I can write debug information to.
Here, I am enclosing a copy of the html file with some examples and
the debug code. Just copy all the code between the script tags and
insert
<script>
// Open the debug window and display debug information
// passing false suppresses all debug information and
// the debug window.
debug(true);
</script>
after the <body> statment.
I used this code to find out that when you looked at 3.00 to determine
if it was an integer, the code was returning false.
