RHC,



For data entered into a sheet, use the Validate feature. If this is too
limited, you can use forms and include much more extensive validation; but
you will have to write a lot of code.



A third trick is to use UDF to capture input, validate (or fix) and write
back to the sheet. Of course the UDF must be in a cell other than the input
cell and you may have to play games with the VOLATILE command to avoid a
never ending circle. This trick is useful when you want to validate a lot
of cells at once on a manual or programmed compute.
