QR code scanning to access Google sheet data

I am new to MIT app inventor and was trying to create a QR code scanner that would scan a qr code and access a specific row on a google sheet. When I try to scan a qr code that contains the number 14 to access the 14th row in my sheet I run into an error that states " invoke: unable to invoke method 'Read Row' in object of type boolean irritants().

What fix is there that can help me and what else may be inhibiting this program to work.

It appears you are attempting to build an ios app using Bluetooth. At the moment, I don't think that is possible.

Try it with an Android device. It might work with an Android phone providing there aren't any coding issues.
