Hi Rylo,

The logic behind this is as follows,
I select the size ( in this case 16 )
Then enter my "grip" being 20.
The result should be the minimum length where the grip "20" is larger than the value in the 16 min column, but small than the 16 max column. This then puts the length at 50 ( column A )
The length is actually refering to the coulmn not refering to the row, 16 or 20 across the top.

Sorry for confusion.
