Hi, "For every unique value of col A - C and col F, then the number is increased by 1 from col G unless there is already a number for that combo in col H, then it gets increased by 1 from that number in col H"
I think I understand the first part of the sentence, but the meaning of the second part escapes me. "unless there is already a number for that combo in col H, then it gets increased by 1 from that number in col H" It appears that there is always a number in Col H, but is it "a number for that combo" ? I can't tell, since it is just a number, and not derived by a formula. Regards - Dave.

I've attached the spreadsheet again if anyone wants to take a look. Is there a way maybe to concatenate some cells and then write a formula?

Unfortunately this isn't working. The formula in col I is referencing col H which is where I originally wanted the formula. There will be no data in col H unless I can't get a formula to work in there, then it will be manually entered. Can you help me with how the formula should look in cell H2 so that it will return the same numbers I manually entered there to show what the formula result should be? Thank you.

The formula for the key should be: =a2&b2&c2&f2 Populate that down for all of the rows. Basically what I built says -- look at the column of keys, if you don't find a match then take the max of all transactions used thus far and increment by one. If you do find a match, use the same transaction number that was used by that key (the combination of a-c2 & f2). You'll notice that it doesn't "reserve" the next transaction that should be used, it just assigns the next transaction to whichever key shows up that is unique. After you have your column built with the key, here is the formula I put in I2: =IF(ISNA(VLOOKUP(G2,G1:H1,2,FALSE)),MAX(H:H) +1,VLOOKUP(G2,G1:H1,2,FALSE)) Fill that down the remainder of column I and you have a working formula that will either give the same transaction number if a key match is found otherwise give you the next available transaction number.
