The formula for AI2 is
=AC2*Sheet2!$M$2*IF(AC2<>1,1,VLOOKUP(V2,costs!A$22:B$27,2,TRUE))
but you need to set the Lookup table as per costs!A22:B27
You can put this somewhere as a Named range, or just refer to the cells directly as shown.
I presume that you didn't want costs!e14 changed, but wanted to apply this row-by-row in Sheet1.
Cheers
