In your original post, you have L5.style.visibility, now your getting an error on l5?
When you type in L5. does a dropdown appear immediately after you type the period? If it doesn't, then it's not recognizing the control name. Sure you spelled everything correctly?
Like I said, I'm at a disavantage because I don't have your version.
PHV - in a snapshot you can't control the visibility of the controls. Anyway, while at this point it would be easier, I would like to figure out why it works on my part, but not his. The trouble is I can't reproduce his work on my version of Access. But, bottom line, it's his choice.
