Trouble with "and" "if" and "or" functions in excel Formula

Hi, I’m having trouble with this excel formula scenario,

I’m wanting cells “M1” and “N1” to be user input.

If “M1” = “T” and “N1” = “5” then = “F1” or if “M1” = “T” and “N1” = “6” then “F2”

or if “M1” = “T” and “N1” = “10” then “F3”

Thanks.

Welcome to the forum.

Pleae take a few minutes to read the forum rules, and then amend your thread title accordingly.

Thanks.

I am guessing that the latest title is acceptable but it would perhaps be better to revise to something like "Conditional Output"

=IF(M1="T",IF(N1=5,"F1",IF(N1=6,"F2",IF(N1=10,"F3","?"))),"?")

the question marks are to account for situations whereby none of the specified conditions hold true (ie either M1 is not T or N1 is something other than 5,6,10

(if it's not possible for N1 to be something other than 5,6,10 then the above approach can be adjusted accordingly - ie IFs removed)
