Im using the BluePrint scripting from the steam multiplayer from unreal engine, need help with adding something

I got the saving down I was able to add full steam functions working great. the big problem I’m having is I’m using a level up system for my character also with a UI that displays xp and level etc… and I don’t know how to combine it with this system and using the pre made save functions with this tutorial. I really need help I could take screen shots if you would like?
