>Is the InteractiveChange Event triggered by a change in Listindex?

Try putting a wait window in it and find out. Also, you can use Event Tracking to figure stuff like this out.

Anyways, the answer is no. Why? Because it wasn't the user didn't choose it from the listbox interactivly. Event tracking tells you can use ProgrammaticChagne to trap that.

Most people like to add a hook to thier controls called ANyChange() fired from both Interactive and ProgrammaticChange()s.
