I'm trying to add A&M In-Wall Brackets to the foundation in spreadsheet and can't figure out how. I see that all of the brackets show up in spreadsheet "L" in Lookuptable, but somehow they are formula driven (=RANGETOSTRING(LookupTableBrackets,"|")?

 I added the bracket to my hardware and now what it to show up in the drop down list in product prompts. I'm new to the Foundation Library and trying to figure out how it works compared to the Component Library.

Any help would be appreciated!
