Gui Slots Acting Weird

[shucke]

Hello,

I am trying to open a GuiContainer when clicked on a button when in a GuiScreen.

the gui opens just fine but when i try to drag some items to the slots they start to act all weird.

sometimes when i click on 1 of my custom slots i drag out my armour for some reason.

and when i try to move around items in my player inventory it acts all weird.

the items duplicate to the slot nesxt to them i pick up items i didnt even select and all that kind of stuf.

i hope someone can find what is wrong with my code cuz i cant find the error.

 

anyway here is my code:
