First, note the proper syntax for the IF() function: IF(logical_test, value_if_true, [value_if_false]) The logical_test is B2 <= 2. The value_if_true_ is 0. The value_if_false (i.e., if B2 is > 2) is B2 * 25. So the formula is =IF(B2<=2, 0, B2*25). For example (data starting in B2, formula in C2):...
