Issue with Filter issue scope (AQL) from an asset

[Remy]

Hi All,

I'm working on a form that is intended to filter down choices based on previous choices. 

I have an object which determines the "tier" staff can choose. I'm trying to use an AQL filter like the following:

"Tier" = ${customfield_11461.tier}

where {{customfield_11461.tier}} is a value from 1-6, but it doesn't seem to work. I'm wondering what I'm doing wrong.
