Thanks for posting a link to your site. Weebly employees are not able to assist, but I know there's a few users on here that have been known to help out with coding questions from time to time.
The only thing I would caution is to do your best to keep the edited code under Settings>SEO>Header. If you edit the code under Theme>html/css your site will be labeled "custom theme" and it can be a little more difficult to request support if you run into an error with your site. Support reps are only able to troubleshoot sites that are using a standard Weebly theme. Placing your code edits under Settings>SEO>Header/Footer will prevent it from displaying as "custom".
