Buildings, and how to add them ???

Hi all.

I've been playing around resurrecting some of the buildings already in MTW (forester, salter, leatherworker, weaver etc) and adding some of my own (wool grower, cotton grower, cattle breeder etc) to add flavour, explore new avenues for fundraising and hapiness, and to see if I can...

While I can use BIF graphics already supplied for the former, and can substitute graphics for the latter, I'm having a problem with my building infopics.

For example.

"Forester" already has a BIF graphic, and I use the "workshop level 1" for the infopic page. There is already an entry for "Forester" in the Loc/Eng/Descriptions file, I've added entries in the Name file (name, completed & detroyed).

However, when I right click on the icon in the build options menu (which works fine, displays the correct name etc) I get the following message on the info screen...

!!! Can not translate !!!

Obviously, I've forgotten something somewhere, but I can't figure out where.

I've downloaded a lot of mods, but nobody else seems to be adding buildings, but I hope somebody can help be out here.

Cheers,
