Coding Script appearing on mobile page

Hi there. I am seeing coding script about trying to get property guide of non-object on line 36 etc on my iphone version of my website homepage. Looks okay on my desktop. I also don’t see menus on the mobile version. Is this a theme-related issue or a Word Press issue or…? Wish I could paste a screenshot of the issue.
