It wasn't a suggestion Jim. It was an illustration of concept. I also pointed out that more apposite help is unlikely without some more information coming from yourself.
While your latest post is some more information, it is little more than an indication of what cannot be relied upon. I now know it's not that particular control that you need to refer to, but you give no clue as to whether there is another control on the form that can be referenced, or alternatively, if a separate reference to a table is indeed required (which is unusual), how the specific record in that table could be identified.
The point I was making wasn't unimportant. I suggest you need to consider that before posting again. We're generally willing to help, but you need to put some effort in, even if it's only to explain your situation clearly enough so that we know what the question is.
