Need help please, On Register Screen, I am calling up air table spreadsheet to check if user email is already in email column but somewhere I am coding wrongly and not getting the list checked due to row index number (I think). Project :- [https://x.thunkable.com/projects/5c0221f3b5f0362dad71e3a1/Register\_Screen/blocks](https://x.thunkable.com/projects/5c0221f3b5f0362dad71e3a1/Register_Screen/blocks) Please help me fix this. Regards, Navneet ---

I am a super super new user here so please take my thought with a grain of salt. Whenever I am looking processing variables, I want to see what the variable is getting. Unless someone has a better idea, I would suggest setting up a temp label, and then passing the appIndex value to it, so you can see what it is doing. Is there a better way to see the activity inn action? ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/3/e3623dc6b99d9171c46b46566eca8c4052dab08a.png) ---

Good idea, will use a temp label to find what is going on in there. ---
