Thanks Rav, your a life saver.
Just did a bit of checking and I needed to update 985 stocks with new unit amounts since my last update.
Accuracy I've worked it out to 2 days. (Figures all are correct on the 4th Aug) some are correct on the 5th but not all. Guess it depends when they update the figures.
Now all I need to do is annoy you once a month for a new fresh table to keep everything in order.
Thanks once again.
