Custom excel function not updating

Volatile to your function if you cannot find a way of of entering the offset cell as a function argument.

I am having to click on the formula bar, then I have to click enter for the formula cell to do its thing. F9 and Shift F9 didn't help and left the values the same.

Ctrl F9 not only updated the values, but fixed the problem so it didn't happen again.

My solution was to find an old version of the same excel spreadsheet which was not having thses issuesbefore I archived it, which is of similar size and complexity to the current version.

Can someone imagine using Microsoft Excel without formulas? And hardly anything could compare to the frustration caused by Excel formulas stop working all of a sudden.

And how do I get my Excel to calculate and update formulas automatically again?

Don't worry, most likely your Excel is all right, and you will get all the answers in a moment.

Three attempts later and it was still adamant it wanted to be "Manual" and nothing else.

Copy the contents of the spreadsheet to a new one, and deleted the old one (it wasn't a particularly important spreadsheet, thankfully), and everything was fine.

I had a case of this just now on Excel 2010: a particular spreadsheet that would not auto-recalculate.

I changed the setting as indicated above; but the auto-recalculate still did not work, and upon rechecking the "Calculation" option, found it had reset itself back to "Manual" all by itself.
