Link CC dropdown to dependent dropdown AND text box

[trailrunnertcm]

I'm very new at this. Before 3 days ago I hadn't worked with VBA at all, so please bear with me as I try to explain what I'm trying to do.

I'm creating a template, and what I'd like to do is
1. have a primary content control dropdown list,


2. have a dependent dropdown,
3. and a dependent text box that auto-populates
**Also, the three content controls are not successive (there's a date picker right after the primary CC).

I know how to create a primary CC dropdown with dependent dropdown, and I know (conceptually) how to create a CC dropdown with a text box that auto-populates based on on the CC's Value. Is it possible to have all three? Please see attached additional details. Any help is MUCH appreciated as I fear racking my brain any longer might cause me to spontaneously combust.
