I've tried several permutations of Index / Match etc but still not able to alter or amend the following formula as required :
=VLOOKUP(B7,Sheet1!A5:C10,3)-Offset(VLOOKUP(B7,Sheet1!A5:C10,3),-1,0)
Basically just want to lookup one value and then subtract same reference from previous row in lookup table.
I know that offset and vlookup don't work together and it looks like there's quite a number of posts on this topic but as yet still struggling with solution.
Any help much appreciated....
Best Regards,
Spike
