so the value selected is depended on a value that is put into a size column in the spreadsheet - where it is selects a 'band' <0.3 , <0.4 etc
The new tables which I want to search have more 'bands'

I think this is what caused my attempts to get it working to fail.. is there a way where I could show / attach the file as a lot of the formula rely on results of other formula and I could possibly be barking up the wrong tree about where the solution lies.. any insights though would be more than appreciated!
