Hi Majid!
If you mean fix the maximum value that can be put in any cell in a
column:
Select the Column
Data > Validation
Select either "Decimal" or "Whole number"
Put in the allowable minimum
Put in the allowable maximum
"Follow you nose" with Input Message and Error Alert Tabs
OK
Rather than apply to every cell in a column, I think that applying to
the range of actual or potential data entry would be better.
