Hide/Show Command button based on cell value

I am trying to write a code that allows a command button to be hidden on spreadsheet till a value of cell is displayed.

here is an example to the code:

Private Sub UserForm_Activate()
    Sheets("Sheet1").Select
    If Range("$A$1").Value = 0 Then
        Forms.CommandButton1.Visible = True
    Else
        Forms.CommandButton1.Visible = False
    End If
End Sub

The button still remains visable regardless of cell value that is am using as a reference "A1". As a side note, I am also looking at a way to add additional command buttons that will follow the same idea just different conditions. Any help would be appreciated. Thankyou in advance
