# How Do I Create If/Then Statements?

I have 2 columns – A and B. Column A will either be 11,12,13,14. Column B will either be 12,13,14,15. I want to have a formula in Column C that will result in a specific number (19,20,21,22,23,24) depending on the values in Column A and B.

A B. C
11. 12. 19
11. 13. 19
11. 14. 20
11. 15. 21
12. 12. 20
12. 13. 20
12. 14. 21
12. 15. 22
13. 12. 21
13. 13. 21
13. 14. 22
13. 15. 23
14. 12. 22
14. 13. 22
14. 14. 23
14. 15. 24

What you probably want to do is to use the Lookup function. See https://macmost.com/a-simple-numbers-lookup-example.html Watch that first.

So you will create two tables. The first table has the lookup values, like 11 and 12 in the first two columns. Then column 3 will be the formula CONCATENATE(A1,”,”,A2) which will give you the text “11,12” in column 3. Then column 4 has the resulting value, like 19.

In your other table, you have the left two columns for those two numbers, like 11 and 12. Then you have LOOKUP(CONCATENATE(A1,”,”,A2),Table 1::C,Table 1::D).

So in that second table the 11 and 12 are turned into “11,12” which matches the “11,12” in table 1, and gives the result 19.

Thank you very much. I created the table.
