Hi @thasenbo
If you are using SharePoint list to build your power app. You may be referenced it as "Name" in your SP lists, when it comes to the power app. You have to check the internal name of the column by going into SharePoint list settings.
Try the below
Step 1: In your gallery > Select the field
Step 2: In the formula try referencing it as ( Screenshot for reference)
ThisItem.Title

Hope it helps.
