I’m guessing that you need to double check the indentation on your second for loop in your function. But, it’s difficult to tell b/c your code isn’t formatted. Please format your code by using “</>”.

Alternatively, you can also use search here in the forums, as some other posts on this very issue might give you a hint as to what the issue is. But, like I said, move the indentation around in your function.
