Help Dispatching Events on excel commandbar buttons

[Eric]

I have the following function which creates buttons on Excel
commandbar. The problem i can't get the buttons to hook up to events.
For example, if i create four buttons only the fourth one fires the
ButtonEvent, the rest do nothing. What am i doing wrong.

Please help

Eric
