Hi @XITUZ

Thanks for posting here and welcome to the community!

This is actually quite subtle but you are using formatted quotes, which cannot be parsed correctly.

So the quotes you are using are curly quotes used in formal writing or typesetting, You need to clean the format and use straight quotes.

” vs. "

I hope you can see the difference?

If you cut and paste your code into a plain text editor and then back into the node that should help to clean the format up
