Glad you got it. Yes, without the http in front, it would be a relative link to whatever page you're currently on.
In case you didn't know, in addition to the Like module, you can also use the Like easy-tag, like so:
{JFBCLike url=http://www.mysite.com/great-page}
If you need anything else, just let us know!

"LIKE" link isn't correct
