I'm using a copied Javascript code to scroll text across my screen. I would like the text to be vertically aligned in the center (now it is too high), but the code is too complicated for me to figure out. Can someone please take a look at this and tell me how to align the scrolling text in the middle?

Here is the page URL:

Here is the code:
