Hello, I have a
ListBox = firmList
TextBox = firmGroupID
Worksheet = RelatedFirms
ColumnA = gID (ID numbers)
ColumnB = firmName

I am trying to populate my list box based on the value of firmGroupID. Currently I have a combobox that populates the gID number in firmGroupID depending on combobox selection. I would then like the firmList to populate with the list of firmNames based on the firmGroupID. Sheet RelatedFirms contains the assigned gID for each firmName.

This seems simple but everything I try doesn't seem to work.
