Choice component not work on tab

My app’s URL:

I’ve added a choice button. Have it configured from a column from another sheet and have selected a destination column on the tab sheet. However, it’s greyed out and won’t let me select a choice. It’s on my TRQ Answers tab.

That link will not launch your app, you would need to provide the apps share url. i.e. You will have to share your spreadsheet as well in order for anyone to help with your issue.

It’s working now.
