Mobile Menu No Worky!

1VISION

Ok, Ive bet you've heard this before... My Mobile Menu Is Not Working Properly. I have searched, researched, checked forums and I am all out of juice and time! My site is No Worky! I know just enough code to get myself in trouble, which is not helping my cause. It seems to just be on the iPhone6 and iPad sizes. Kind of a problem. I read the latest thread on this but it doesn't seem to be the same issue.
