Have multi-tab Spreadsheet with much cutting and inserting of rows for
updates. Each tab is period in time with lots of formatting and graphs.

To 'simplify', I copied and Paste Special (values) entire worksheet onto
itsself to remove formulas and 'simplify' the entire workbook. Saved and
re-opened the file. Still got the error.

I have EXCEL Professional , Windows Office suite 2003.

Well, you have, as Excel is trying to tell you, too many different formats.
You need to reduce the different formats you are using. Click on the
intersection between rows and columns (or CTRL-A twice) to select all cells
in the sheet, then click on Arial (for example) with 10 pt - all cells will
take on this setting. You can change other font attributes at the same time,
such as bold, italic etc (to get rid of them).

Repeat this for the other sheets.

Hope this helps.
