Delete item from Collection via Listbox?

All,

I am a beginner with VBA and have hit a brick wall with the following:

I load every item within my persons collection (colPersons) to a listbox (lbCollection). This works with no problems.

I want to be able to click a button (cmdDelete) which will remove the item i have selected on my listbox from my collection.

Any help would be very much appreciated.

Kevin.
