Hi,

Are you using the button from View, Toolbars, Forms or View, Toolbars, Control Toolbox? If you're using the second type then doing what you want is fairly easy...

Right click the worksheet tab and choose View Code. Then try something like this:-

Private Sub Worksheet_Calculate()
CheckA1
End Sub

Private Sub Worksheet_Change(ByVal Target As Range)
CheckA1
End Sub

Sub CheckA1()
If Range("A1") <> 0 Then
    Me.CommandButton1.Enabled = True
Else
    Me.CommandButton1.Enabled = False
End If
End Sub

You'll have to change the name of your command button to match the name of yours.

HTH,
