Choice filter not working

[DamianSmith]

I'm have trouble getting my choice filter to work. I'm new to using survey123. I'm trying to filter pre-existing  locations based on an installation as we have locations which have previous conducted survey. I want the pre-survey points to be filtered according to which location they are at. No matter what I do, my pre-survey choices remain blank unless I remove the filter,

You give it the name of the column to do lookup on, then the value to match in that column. It already knows the list name so no need to repeat that.

installation=${installation_1}

Hope that helps
