How can I disable some field in Form?

[acin0026]

I have a Form which you can choose USA. or International. Then customer will choose state or some countries. (That form shows all states and some countries). I would like to disable other countries (gray options) if they select USA. Also, if they select Internaional, all states will show gray options.

Could you help me with this.

thanks.

Like this:
IF Me![NameOfSomeField] = SomeValue Then
Me![NameOfAnother].Enabled = False
Else
Me![NameOfAnother].Enabled = True
End if

Make sure that the field(s) you are about to disable do not have the focus or an error will occur. That's it! Gord
