If you need to base a calculation on whether a cell has a number in it or not, you can use the ISNUMBER worksheet function. This function returns True if the target cell contains a numeric value or False if it contains anything else. For instance, if you want to do a calculation based on whether cell A3 contains a number, you could use the following:
=IF(ISNUMBER(A3),(A3*12)/52,"Enter number in cell A3")
This example results in the cell containing the result of (A3 * 12) / 52, but only if A3 contains a number. If it does not (for instance, it is blank or contains text), then the result contains the text "Enter number in cell A3."
