I'd like to know if the following formula is correct?

It gives an error `#N/A` but some googling teaches me that the `importxml` is a fickle thing. It should import a list of 24 values, starting with `57.48`, but since I get an error I just want to be sure that the problem is caused by the function and not by my xpath\_query being wrong, because this is the first time I tried something like this.
