It seems like you're trying to use a placeholder or template variable, but you haven't provided its value. In this case, {{ variables@$title }} appears to be a placeholder for a variable named $title.
If you intended to use a variable named $title, you should replace {{ variables@$title }} with the actual value of the variable. For example, if the value of $title is "My Amazing Title", you would replace it like this: "My Amazing Title".
If you provide more context or details about what you're trying to achieve, I'd be happy to assist you further!
