As you see in the image, I have three options groups. When I check No of G and Yes of B, the ER option will be enabled( I choose enabled false on ER).
Code:
Private Sub frER_Click()
If Me.frG.Value = 2 And Me.frBrand.Value = 3 Then
frER.Enabled = True
Else
frER.Enabled = False
End If
End Sub
Thank you.
