I have this code

=IF(XOR(13>=$Q2,$Q2=""),(($Q2-(VLOOKUP($C2,DATA!$D$1:$E$22,2,0)))*100)*0.02,IF($Q2>=14,(((($Q2-(VLOOKUP($C2,DATA!$D$1:$E$22,2,0))))*10)*0.02),""))
It is looking up a product flavor (from sheet "Data") and matching its blend score (sheet "Data") to determine the necessary adjustment to the equipment. I know I can do this in the userform I just don't know the proper syntax
