Thanks. I wasn't sure what the limit was and that Excel was reading that
there was anything in those columns and rows, which I thought were blank.

I had to select really far over and really far down and remove all
formatting (lines/shading) as well as clear the cells. That worked.

Thanks

Excel has 256 columns. If you "insert" columns, an equal number of columns
are deleted from the far right of the spreadsheet. If you have anything (or
once had anything) in the columns to be deleted, Excel makes you clear out
those columns manually, so that no data is accidentally deleted.

I have a worksheet, albeit a very full/big worksheet, with lots of formulas

it and gives me an error about losing data if I do that... etc. It also
says
something about Blank cells... It mentions clearing out/emptying the
columns
to the right, but I obviously can't do that and maintain all my formulas,

I've searched the Microsoft help pages to no avail.

Any ideas?
Do I have too many columns, or something?
