John I tried your formula, it worked until I substituted the table names in the formula to the cell references that hold them. This is what I was originally trying: =INDEX(I2,XMATCH(F2,I2[Width]),XMATCH(E2,I2[#Headers]))
In your formula I swapped M_30 to I2, it didn't work. Probably a simple answer, but it has me stumped.
