logic operations

when using a logic function how do you combined multiple logic operations?
ex. if b13=3 and f13=480 true=3 false= b13=2 and f13=480 true=2 false=
and so on would it look something like this:

=if(and(b13=3,and(f13=480), "3", if

and just repeat???
Thanks for all the help.

The first part of your formula would be:

=IF(AND(B13=3,F13=480),3,"insert here what you want if either B13 doesn't equal 3 or F13 doesn't equal 480")

Note there are no quotes around the 3. If you want the 3 to be text as opposed to the number leave your quotes in.

I guess, something like this...

=IF(AND(B13=3,F13=480),3,IF(AND(B13=2,F13=480),2,IF(AND(B13=1,F13=480),1,"")))

Hope this helps!
