For your second checkbox field, set both the choices formula and the value to chkOK. This will probably only work properly though, if your new field is computed and chkOK is set to refresh fields on keyword change.
Thanks for your reply, but I forgot to mention that the new field can’t be computed since it must be editable. You could say that the checkbox fields should reflect each other over time.
Ok - i had a feeling it wasn’t going to be that easy! In your situation I’d be inclined to make both checkbox field computed and set their values using a dialog box or something like that. Either that, or hide the second checkbox field and have something in the exiting event of the first checkbox which sets the value of the second and unhides it. Or maybe the input translation event of the first field. Just putting down ideas as they pop into my head here. Perhaps if this doesn’t help, you could describe a bit more about what you’re trying to do as this makes it easier to come up with specific suggestions.
You can do what you’re talking about with input translation formula and keyword formula in the second field. You may also need a hidden CFD field with a copy of the first field, so that you can tell when the first field has changed.
But you need to further specify the problem. What happens if the user unchecks a box in the second field, then changes their selection in the first field? Do you redisplay the second field with all the choices checked, even though the choice they unchecked before is also available in the new list? And so on.
