The problem is still the same… you need to change this:
At least to test it and know if that’s causing the problem (I think it is).
I also don’t see where you are setting the initial value of app variable currentRow. It seems like you’re checking to see if it contains the text input text but the value of app variable currentRow is null.
Edit: okay, you changed the loop variable to i. Now you need to replace app variable currentRow with i.
