"Do a search for" or Document-Backend Query on Page load?

Troubleshooting

Hi,

from bubble im used to work with page/app parameters (worked well) in FF. i get Null errors all the time now. Questions:

1) In general App Parameters seem best suited to work also with componetns etc. I dont have to many 3-5 and just one page, so that should be OK?

2) I have lets say 3 Lists: Projects / Sub-Projects and / Bidder and 3 states for the same; Idea is to say "On page load search latest project - herein latest sub-project and take the latest bidder of the same"

How do i run these 3 queries? How can i select "Backend Query" i dont get it....
