For the preceding line to work, your element needs to have the attribute data-description on it. Does it?

For the preceding line to work, you need to have an empty HTML element with the classname description present in the page, within the container element of the slide (no clue where that means, I'm just interpreting the code for you). If that element exists, then it will be emptied and re-filled with the description.

My guess is that you are missing one or more of these antecedents, and without them, the JS won't have anything to work with.
