This is so straightforward and simple that I’m embarrassed that I can’t find the answer for myself!
I want have a formula in a second cell, whose result depends on the contents of a first cell, as in (trivial example):
IF cell A1 is blank THEN leave cell B1 blank ELSE multiply contents of cell A1 by 10 and place the result in cell B1. Please could you give me a second formula (or more complex single formula) which covers the case where cell A1 is zero (not blank) but I still want to end up with a blank cell B1.
