that should be two single quotes or add a backslash before both double quotes.
If you want to do this, you really need to get yours hands dirty a bit and read about json.

I will try my best with json, java, nodered, python, html, css but I must confirm that I´m better in copy/paste reusing and then change it to my needs.
I really tried to learn but I haven´t had success.
