GSAP SplitText Hover Effect faulter

I’ve created an array of nav links within my navigation. Upon hovering over top of a link, the text moves upward, into overflow which is hidden and is replaced by the same text moving out of overflow from ben beneath. I additionally want to incorporate a GSAP SplitText attribute whereupon hover, not only does the word move upward but the individualized characters stagger upward. However, I’m having trouble creating the code within my pre-existing commands

This is my code:

If anyone has any advice I’d greatly appreciate it!
