Reset ComboBox

[yagerlegi]

I have created a combo box, that when I hit the drop down with one the other will populate.
But once I change to another selection from the drop down, the second drop down will not remove the previous selection.
I would like to clear the information when I change my selection from the first combobox-
Any suggestions?

Like the code here does (Null probably also works)?
