Ok If anyone wants to help I'll email them a copy of the excel sheet, I've got a lookup working, in a different way this time, but its returning the wrong results, and i can't figure out yet.
Just send me a PM with your email address or post on here, and i'll send the file off to you.
The file does have macros but they dont have to be enabled for it, they just make it easier for uses to input/clear data.
Thanks
