You could try calling the following code from the on change event or from a
button object:
Sub EnterNumber(nbr As Integer)
Dim oWorkSheet As Worksheet
For Each oWorkSheet In ActiveWorkbook.Worksheets
oWorkSheet.Activate
Range("A1").Activate
ActiveCell.FormulaR1C1 = nbr
Next
End Sub
> Enter a number into an active Cell and want the same cell in every other
> sheet has the same number entered. Does anyone know how to do this by
> using form?
