hello so I used thie tutorial of mood tracker and the only issue is I want to save amount of times I press the emoji even without without being on the screen. For the happy button, it works, but with the other emojis when I press them it just shows: Runtime Error
The operation + cannot accept the arguments: , [""], [1]
Note: You will not see another error reported for 5 seconds.
Dismiss
What is it that I am doing wrong?
