      I didn't think so, but I went ahead and put the

       <meta http-equiv="X-UA-Compatible" content="IE=8" />
      tag into my master page and tested it. I did a view source first and verified that the meta tag was there, but I get the same 2 js syntax errors.


      So frustrating! 


      Thanks for the tip though!

      Just a stab in the dark here, but could the response from the QA server be putting your browser into IE 7 mode?

      ugg.. the dreaded punt! lol

      I've searched StackOverflow, but I'll post the question over there too.

      If anyone happens across this thread though and has any other ideas, please, feel free to offer them up, either here or via email.

      Thanks for all your suggestions.

      Tim

      I don't think this is really a JSON issue, more a browser issue, so I'd
      suggest going to StackOverflow instead.
