I am working on a site: www.trojansteel.com and have borrowed a handful of scripts to enhance the aesthetic. The desktop side looks great, but as I am building the mobile side, I am noticing a handful of the scripts aren’t transferring over. What’s even more bizarre is that sometimes they work after refreshing a few times. I am testing on IOS Safari in private mode. 

The primary effects I am having an issue with is: 

• Fixed header
• Typed text effect
• OnScroll animation 
  • fadeIn
  • fadeInUp
  • fadeInRight

Can someone who is much smarter than me take a look and see whats going on?

I would owe you a whole lot. =)
