iMacro not filling in facebook comment field

Hey, anyone knows how to make iMacro comment with my own text on facebook pages posts? Like, it logs in, goes to a certain page, then comments on a certain post, preferably the latest one of the page, and done.

All I got so far was to log in, and go to the url, but then it doesn't fill in the field with my comment nor does it attempt to post it.

Anyone knows how to do this? Or at least just some tips on how to? Thanks

Have you tried having it paste whatever is on the clipboard?
