Including files in LUA

I have a hud in my Lua/autorun folder and I need to include in it files from just the lua folder, how do I do it without creating lua errors? Also I need to include files from ULX so I can put the person’s rank into the HUD

ULX should automatically be loaded, you do not need to “include it”, using player:GetUserGroup() will give you the rank with ULX.

Also “including without creating lua errors”, don’t include a file that doesn’t exist, as simple as that, make sure your code doesn’t have any syntax errors.
