I'm sure it won't take long for some helpful person here to do this really easy task that is beyond me.
All I want it to do, when I put a £sterling number in column B, is to do a running total in column D
And it needs to work in, and be savable to, .ODT format for LibreOffice, but I can't upload a file in .ODT format here.
