You haven't written many workbooks for other people to use.

Set up whatever data validation rules you want to ENSURE only integers
are valid entries, type (but don't press enter) 0.125, press [F2],
[Shift]+[Home], [Ctrl]+C, [Esc], [Ctrl]+V.

Try to use event handlers - open the workbook with macros disabled.
