Its actually order quite simply.

Look here.

the number after sm is the Act, and then the number after is the mission. (The SOC missions are the "loop" missions)

Yes. Use a vp viewing tool such as VPView to extract the table files from the vp. Then, edit the extracted table files with Notepad. Then, place the modified table files to either \freespace2\data\tables or \freespace2\modfolder\data\tables to see if they work.

OK.  That's the TBL files.  Would this work with a set of missions and a campaign file linked to those missions? 

[Droid803]

Yes, it would.
Just put it into \freespace2\data\missions or \freespace2\modfolder\data\missions for missions and campaigns.

Would the changes be updated into campaign, or do I need to rebuild the campaign file?

If there are files with the same name in a \data\missions\ folder and a vp, the ones in \data\missions\ override the ones in the vp.

Well, after editing the FS2 campain missions, I tried the FS2 campain and they still ran, but they're not updating.  I didn't change anything about the missions name, the file name, or anything!  All I did was change the team loadout.  I'm going to try to re-create the campain file.  If that doesn't work, then I'll try adding in the back-ups that were made during the editing.

Actually, I've changed where the solutions to this problem will be posted out of fear of..."Thread Hijacking" I think it's called?  Either way, the topic you can go to to post any solutions you may have is FS2 Main Campain with Shivan fighters.
