CodeMirror Editor Not Working in blogger

Hello Dear Expers, First of all i hope everything going fine there.

I am working on Code-mirror HTML Editor and trying to implement it on blogger blog page, the editor is working fine in dream weaver, Dropbox demo page but not working when i am trying to run it on blogger blog page. i am sharing both links Dropbox demo and also blog page where its not working. I really need help of experts.

Working Live Demo on Dropbox:

Live Demo Page on Blogger blog (Not working):

Thank You All Of You In Advance.

The editor seems to work when I open that link. If I press ‘Preview’ I get an error that seems entirely unrelated to CodeMirror.

Thanks for your reply dear, Do you have any idea to fix that. Maybe the idea might be helpful…
