Mustache array problem

General
1

Good evening,
i'm having some trouble about this: after a query in mysql i have this result payload[2][0]["@id"], i need to get this data in a html template using mustache.
How can i do it? {{payload.array.2.0.@id}} doesn't work.
Any ideas?

Thank you!

From the limited info
{{payload.2.0.@id}}
But can't be sure as i have no idea what your array really looks like.

Wow, it worked perfectly! Thank you so much!
May i ask something else? Can i use this value in a if statement in html?
For example: ( if {{payload.2.0.@id}} > 0 ) { some html }

There is a lambda function you could use. mustache(5) - Logic-less templates.
But, it may just be simpler to use a string literal template in a function node.

here is a example of three ways
