Scoreboard API & Scoreboard Help

Hey there, so I have been working on a Scoreboard Teams plugin to show the players rank in the tab menu! And I got it to work, but it would attempt to create the team every time the server is launched and throw errors, so I turned it into a mini-api, and created a plugin so every time a player joins they are added to the team.

Any help or guidance to making this work would be appreciated!

EDIT: Credit to Skionz for this: I forgot to mention to new issue, the actual plugin for Tab List will not load up in the server at all!

 

@FlipSide_Mike And what is the issue? You tell us that you resolved you problem yet you ask for help without telling us what the new problem is.

 

@Skionz The 2nd plugin doesnt load in the server, it wont enable, it wont do anything, as if it wasn't in the folder, and I believe its because the API isnt in the folder with it, yet it cant because it wont allow the server to launch more than once!

 

@FlipSide_Mike Why make to separate plugins? Just make a class within the other plugin. The API has to be in the plugins folder as well as the actual plugin. I stack-trace would help further.

 

@Skionz I figured out the issue, I created a loop to check if the team was already made, and it works, but I'm getting an error on the onJoin method

            VIP.addPlayer(player);
        } else {
            MEMBER.addPlayer(player);
        }
    }

Line 94 is where the error is, is the
OP.addPlayer(player);

And because of that I figure its occurring ever time a player is being added to the group
