That won’t work as for starters you are missing your page onReady function underneath the import line.
Plus, either you need a event handler to run the query or to write it into your page onReady function so that it runs when the page loads.
Have a look at this tutorial here as it keeps it all on the same page.

Finally, if you are calling something from a dataset, then just do it like in this tutorial from the same website.

Also, if you do use getCurrentItem, then make sure that you have the dataset wrapped up in the page onReady function with it’s own onReady function.
