I have a sharepoint list set up like the attached screenshot.

Each line has the company, and then the prices they charge for shipping the boxes.
I'm trying to create a search app in powerapps where a user can select from a dropdown the name of the company, and then enter the amount they want to ship and the gallery will spit out the price of that shipment. Currently, I can get the search to function correctly when searching by company name, but trying to further filter this down is not working for me. Is there a way to get dual searches to work on one sharepoint list?
