VBA to enable a field based on option in combo box

[Ant_Snell]

I have a combo box on a form named “Bill_Payer” with a label of “Who will be paying for the therapy? Most options are bill payers with an additional option of “Other” option ID 12. The next field is a text field “BillPayer_Other” with the label “If other selected, please specify:”.
The text box “BillPayer_Other” is not enabled. I would like this field to become enabled only if “Other” option 12 is selected in the “Bill_Payed” combo box and if the content of “Bill_Payer” then changes to anything other than option 12, clear the content of “BillPayer_Other” and re set it to not enabled.
Can anyone help with the VBA code to do this please? Sorry I am sure this is quite basic but novice level when it comes to VBA.



Thanks

In the afterupdate event of the BillPayer control

If Me.BillPayer = 12 Then
    Me.BillPayerOther.Enabled = True
Else
    Me.BillPayerOther.Enabled = False
    Me.BillPayerOther = "" 'Or Null of you prefer'
End If
