PowerApp Developer Assistant on Current App

I am trying to fix errors,issues, integrate new data/ capabilities depending on end users role to my shipment tracker app I am currently in the process making. I’m having issues with a few things that I am currently adding like the repeatable table not viewing on the shipment tracker screen once it has been submitted from the new request screen. All the form data populates just not the table info for that specific request, which does not show the gallery of the table for the material requested at all as you will see in snipits uploaded. . Also, need to work on individuals only having access based on their role to certain parts of the screen. If they need to update information it updates additionally to what has been updated but captures who made the update and when I’m the history of that request. I need to add a gps pin current location to outbound shipments of material is not at the whse and needs to be picked up in the field. If the material requires HEO assistance (crane and rigging) it notified that department when the yes is indicated and submits them an email of all material details. If we need to delete a request only certain individuals can delete it to know why to capture kpi metrics on why shipment request are being deleted and how we make sure shipment request are not being submitted twice is that possible to do? I have more I can discuss on the app as well. I can submit snipits off my different screens if needed so you can understand the application more. The file I currently submitted is what I have for my repeating table but it is not working as needed.
