Thank you. Using the counter0 as an index into a list seemed like an
obvious use case to me. So I give your 'get' filter idea a +1.
Thanks for the CSS idea. I found an alternate solution using the <COL
align="left"> tag to set the alignment on a whole column so I only have
to loop thru the align list once. More efficient than what I was trying
to do originally.
Thanks,
Michael
