I have the following code:

If Application.RoundDown(Left_Cell, 2) = Application.RoundDown(Cp_1, 2) Then SectionBottom = Cp_1 - (O_1 / 12): Exit Function
What I would like for it to do is to continue to execute the above function if O_1 > 0 or O_1 < 0, but if O_1 = 0, then to ignore the code. So in effect, if O_1 = 0, exit the function without assigning a value to SectionBottom.

Any advice?

Thanks.
