Requery listbox that uses a function as a rowsourcetype

[J.Allen]

Hoping someone can help - I am using a function to populate the data in a listbox from an array. It works fine, except when I want to requery the listbox to show changes to the array. When I try the requery method, my listbox ends up full of blank rows.

Does anyone know how to requery the listbox so it shows the new values in my array?
