Hi,

You'll have to do this as a little macro. Go into the VB editor and add
the
following into the relevant Sheet.

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column = 5 And Target = 100 Then
Cells(Target.Row, 1) = 100
End If
End Sub

You might want to check for ABS (target - 100) < some small number rather
than equality.

Hi,
I'm trying to set up my worksheet so that if the value in column E is
changed to 100%, the value in column A of that row automatically changes
to
100, regardless of its original value. At the same time, I don't want to
lock down column A - the user can enter any value in here when E is not
100%. How do I go about doing this? Do I need to write a macro?
Thanks!
Amit
