Invalid translation meta tag (Google Translate widget)

Question

I implemented the Google Translate widget on my website, however the translation into my native language from English is small. I would really like to be able to correct the translation or combine the Google translation using custom translation, however, each article I read stated that I should get a meta tag for custom translation, for example:

However, I only get div and script tags at http://translate.google.com/manager/website/

Any way to get the setup ID or any way to seamlessly execute a custom translation would be appreciated
