I get the following message when I try and increase the significant digits
of
a number in a cell, with certain Excel files:
"No more custom number formats can be added"

The message comes up in a pop up box. Once I get this message, I get the
above message everytime I try to re format a cell. Does anyone know how I
can aviod this message?

Thanks,

Remove some of the unused custom formats!

The problem is that these build up rapidly, particularly if you have more
than one workbook open at a time, as formats from all open workbooks get
saved each time any file is saved.

In the section "POWER PROGRAMMING TECHNIQUE By Leo Heuser" you will find a
very useful macro that will delete all unused custom formats from a
workbook.
