Ok so i made a gui that opens up when you press a button, it shots like level, exp, stats ect ect, how do i call these int variables from a plugin or must i set them for every player via the mod ?

This needs more explanation.

 

GUIs are client sided displays. You don't call values FROM them. You put values INTO them (onto display).

 

Do I understand correctly - you have server-sided plugin that holds values about players (stats), and you want to display those values in player's GUI (as Forge mod)?

 

What API is your plugin using?

 

Basically you will need to setup packets server->client.

pretty much, i have spigot 1.8 for forge 1.8, i have the gui, and i want to insert values obtained from a plugin.

Could I ask "Why???".  Why are you using another Client side mod system instead of just doing it all in Forge.  Or perhaps, spigot has changed since I last messed with it. 

 

If you have just Forge questions, we can probably help.  If you are looking for spigot, need to look elsewhere.

I think they have a server (that doesn't run forge) and they want players to be able to log in without forge. BUT they can install an optional client mod to improve their experience. That's what I gathered from the post

Look at this: http://www.minecraftforge.net/forum/index.php?topic=28953.0

i had no idea im able to do this all in forge if i can make guis, and scoreboards on the screen then no need at all for spigot!
