Sorry, much too much information again. Don't complicate it by telling us about which bits do work or used to work, just pick out the bit of code that is not working and show us that. Put debug code in so that you can tell us what data is going in and explain what is going wrong. We have not (or at least I do not) have time to wade through all that information. If you have multiple problems then start off with just one of them. There will only be a dozen or so lines of code so just put it inline. > > 1 beer for anyone who can help guide this lost soul :) I am doing my best, but you must keep the question simple.
