Thanks for the Quick reply!
Doesn´t this template already come with a scrolling script somewhere that can be modified? The scrolling effect works well when linked to module positions such as: #gkHeader, #gkTop1, #gkTop2, #gkBottom1 and #gkBottom2, but when I link a menu item to the Intro module position using #gkIntro, nothing happens. I would just like to know where I could find the original script that this template uses to make the modification before adding the script you suggested that is most likely my best option if I can´t find where the original script is.
Thanks!
