Got it working for the most part. Not knowing exactly what belongs where for this mod, I copied some stuff around between my mod folders in my Arma 3 directory and the features all appear to be working properly. I still get the error messages on game start, as well as in game at mission start, but they don't appear to have any major affects that I have seen in about 20 minutes of tinkering. There are two things that I still have questions on though...
1) Is there a way to customize the gear/loadout of a member of my squad other than my character?
I've tried selecting a unit and going to the "actions" menu and selecting "gear customizer". The unit will run to the nearest ammo box, but it only brings up my current player rather than the other unit I've selected. Not sure if there's a way to accomplish this other than making all units playable and then switching to each one and running up to the box manually to change gear/uniforms/etc.
2) The menu of the gear customizer is not visible in any menu size other than "Very Small" and "Small". I really don't mind playing this way, but it makes other functions harder to read in the game. Is there a way to shrink down the gear customizer menu (or gui) in the settings part of the mod? That way, the full gui would show up even when my game menu size is set to "High".
I don't know if those are supposed to be regular features (and I still have to tweak files around) or if they are not possible as of yet, but you guys definitely have more expertise doing this than I do. So far, this is the most significant change to the game I've seen from any of the mods I've downloaded and I'm absolutely thrilled that most of the features are working now. GREAT MOD!!!!! :-) Gliptal, thanks for all your help so far!
