listbox always selects index 0

I have a listbox for entering phone numbers (lbxPhone). The UI gives the user the ability to remove items from the listbox (single-select) by selecting a phone number and clicking the Remove Button (btnRemovePhone).

The problem is that no matter what selection is made, the item at index zero is removed. Here is the code for btnRemovePhone:

Code:

Protected Sub btnRemovePhone_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemovePhone.Click
    lbxPhone.Items.RemoveAt(lbxPhone.SelectedIndex)
End If

lbxPhone.SelectedIndex always returns zero. How can I get it to return that actually index of the selected item? What am I missing here?

Make sure all the items in your listbox have a value and that they are unique.

That was it. Thanks.

What was it.. no values set, or duplicate values?

Oops, sorry. I had values set, but there was a common scenario where there could be duplicates.

Ahh ok, I have run into that before. I would be nice if an error occured while binding to you let you know of the problem.
