No Selection in Listbox

Hi,

In a listbox, I am utilizing the On Select event. When someone clicks on an item, I want something to happen.

However, when the listbox is populated, the first item is selected. If someone clicks on the already selected item, then no On Select is fired. I want to have no items selected, so that when an item is clicked on, the On select will be fired.

If possible, I would like the On Select event to fire, even when an item that is already selected is clicked on.

Any ideas?

Thanks.
