Conditional sum calculation

Conditional sum calculation

Hi everyone,

I have a bit of a brain teaser in a Zoho spreadsheet. I'm attempting to do a sum on a cell if another cell is not empty. It's a very simple calculation, but I'm struggling with getting the condition to work.

If cell B3 is not blank, I want to deduct the amount in B3 from a fixed amount (22000). Essentially it's a running total showing how much is left to accrue. I want to use that formula in C3 and then repeat it down the rows.

I've tried all of the following in cell C3:

IF(B3!null;=SUM(22000-B3);)
=IF(CELL(b;B3);””;(SUM(22000-B3)))
=SUMIF(B3,”<>”,(22000-B3))
=IF(B3=“”,””,(22000-B3))
=IF(B3<>””,(22000-B3),””)

And they all error (with '#NAME!', indicating a typo of some sort in the formula).

Any assistance / pointers appreciated.

Thanks in advance,

James
