Modules & VBA :: Selecting Combo Value Changes Checkbox On Other Form

I have form 1 that brings up a record, I then open up form 2 with that record details.

On the 2nd form I have a 'status' combo box with values 'OK', 'bad', 'unsubscribe'.

I want to change the value of a checkbox, 'Active', on the 1st form, 'Maildelivery', from true to false if the combo value is changed to 'bad'

Here's the code:

Private Sub cmb_status_AfterUpdate()
If Me.Status <> "OK" Then maildelivery.Active = 0
End Sub
