Power Platform Community Forum Thread Details

I am trying to create an editable grid in Power Apps. In the blank gallery I created (embedded in a container), I have added, amongst others, two dropbox controls that I link to choice columns in a Dataverse table called Gridtests. One of the choice columns in the Dataverse Table called 'Gridtests' is the 'Contract' column. However, when I enter the formula Choices(Gridtests.Contract) in the property 'Items' of the dropbox control, I get an error message as mentioned in the subject and as shown in the screenshot below. And I do not understand why. Is there anybody that has any experience with this error and how I should/could solve this? Below a screenshot of the error message that pops-up.
