I am working on my first app in powerapps and I have two sharepoint lists that I have our inventory of disposable supplies in one list and I have the other list to record all transactions that take place (taking supplies or restocking). the app is able to add new items, delete items, edit items, scan a barcode to pull up an item, then take items or restock them. I have tried to use the patch and collect syntax to have it collect the data and store it in the other list but everything I try does not work. Help!
