Thank you very much Marco,
thank you very much Michael!
Good to have a script that works so I could figure out my mistake:
I tried it that way - it's a bit embarrassing- but my quotation mark was changed automatically by the text editor.

Hi Jay, your text editor sabotaged you! ;)

Sometimes the fancier "word processing" type editors can be bad for editing program code since they can sometimes mutate the text like that.
