You are limited to 7 IF Statements nested together in a single cell.

You are returning the same results for 1x, 2x and 3x (0%). Also, 9x, 10x,
11x, 12x (6%). You can combine these in an OR function:

=IF(OR(C17={"1x","2x","3x"}),0%,IF(C17="4x",2%,IF(C17="6x",4%,IF(OR(C17={"9x","10x","11x","12x"}),6%,""))))

If you want to use just 1, 2, 3... instead of 1x, 2x, 3x... make sure that
C17 contains just those numbers, then change your formula accordingly.
