Answer 1

Hi,
Please from now own put this exact tag => (So that's: four characters, forming the word 'code' between curly brackets)
before and after your examples. That way your indentation and formatting remains intact and we will be able to read and understand faster what's going on.

any clues?
Probably all you need to do is call your function once more or reconnect.
