I would enter the formula as follows (based on your example) in X1:
=IFERROR(VLOOKUP(B1;B$20:Z$22;25;FALSE());0) The "IFERROR()" is used to return a value of zero in case the lookup fails, which corresponds to the last selection when false in the string of nested IF() functions you listed. You can also re-write the formula like this: =IFERROR(VLOOKUP(B1;OFFSET(B$20;0;0;<number_of_entries>;25);25;FALSE()) ;0) where <number_of_entries> is replaced by a formula that counts the number of entries you have in r(2). This way, as you add entries, the formula dynamically adjusts itself to the correct count of values and you can drag this formula with little risk of error; depending on what you are counting COUNT() or COUNTA() would work for you. Additionally, you could assign a name to cell $B$20 and use that name in the formula instead of an explicit reference to the cell. Alternatively, you could use the MATCH() function to locate on which row the company name is and then use INDIRECT(ADDRESS()) to retrieve the value you are looking for. This is slightly more complex and in my mind does not really perform better than VLOOKUP() in this case, but it remains an alternative. I hope this helps.
