thank you very much for that :-)
it helps a lot!

One more problem tho: Do both list have to have the same number of rows for some reason? Cause it works fine in the beginning of my list, but not in the end. So it shows me on 'available' but I know there must be more... So the list in sheet 2 is much shorter than the list in sheet 1. Could that be the reason?

Thanks sooo much for your help!!!
