Let's assume that the user's name will go in column B across from the "X"

Enter the following worksheet event macro:

Private Sub Worksheet_Change(ByVal Target As Range)
Set r = Range("A:A")
Set t = Target
If Intersect(r, t) Is Nothing Then Exit Sub
If t.Value = "X" Then
Application.EnableEvents = False
t.Offset(0, 1).Value = Environ("username")
Application.EnableEvents = True
End If
End Sub

REMEMBER this is worksheet code, it does not go in a standard module

Hey,

We have a shared workbook in which we want to record the user's name when
they enter an "X" in column A.

Is there a way to do this?

Thank you
