Hello,

This may be a simple one, but I'm kinda in a hurry and can't make it work. Here's my problem...

Column A Column B Column C (formula)
1 4 4
1 5 4
1 6 4
1 7 4
2 5
2 5
3 6
3 6
3 6
etc

In column C, I wanna return 4 for every 1 in column A, 5 for 2 in column A, 6 for 3 in column A etc. I've tried simple Logical functions and VLOOKUP without any luck.

Can anyone give me a formula, please?!

DK

Hi DK,

I can think of two solutions, but both have a downside:

1. IF function. Downside: maximum of 7 criterias.
Only use when the number in column A doesn't exceed the number 7.
Put this formula in C1 and drag it down: 
=IF(A10=1,4,IF(A10=2,5,IF(A10=3,6,IF(A10=4,7,IF(A10=5,8,IF(A10=6,9,IF(A10=7,10,"")))))))


2.VLOOKUP function. Downside: create an extra table.
Use when column A exceeds the number 7 and there isn't any other solution available.
Use for example column G to input as much numbers as nessecary and put their counterpart in the column next to it like:
1 4
2 5
3 6
4 7
5 8
6 9
7 10
8 11
9 12
10 13
Then use the following formula in C1 and drag it down:
=VLOOKUP(A1,$G$1:$H$10,2)


Hope this helps,
Trowa

Hi DK,

Since you're just adding 3, why don't you try: =A1+3.

Best regards,
