the "Add Comment" button on the View Message page is not being controlled by Trans

Yesterday I edited the Trans to match Curriki style and make the View Message more consistent. See for instance:

http://next.dev.curriki.org/xwiki/bin/view/Messages_Group_CurrikiLeadersGroup/HospitalforSpecialSurgery

In the Trans, the string and display text for the button for adding a comment looks to be:

groups_messages_view_addcomment_btt=Add a Comment

However, the button text on the page is not reflecting this, and is showing only "Add Comment."

Please make the page refer to the Trans for this button.

Thanks!
