Multiple XML files storage is not working

Hello every one. Guys I really need some help regarding giving the player three different slots to save game. I have set everything fine and load and save game is working pretty fine. The only problem is when I save the data in one slot it overwrites it in all the slots for some odd reason. I have different file names and different global variable are controlling which slot is being used to save the data. Can anyone help me please.

The first pic “save 1” is an external event called savegame. second pic “save 2” is from the second level (scene) which is same in every level. third is from the menu scene.

Guys I know there is a spelling problem. I have corrected it and still the same problem.
