Inventory System Widget Problem

Hello, I’m having a issue with the inventory system in my game. I got it so it adds a child and all that in my widget. But for some reason It wont let me call any variables thats associated with it. Such as the name for the child widget or the drop sounds etc. I can grab the name out and set it but it comes back blank. same as the sound, I can get the drop sound variable and set it to play sound but it plays nothing like its empty. please help, thanks!!
