i put all scripts and every thing in correctly but however when i put a random npc down with a battle event it just has the default battle system on can anyone help me to solve this and how to get the battle system working?

I don't know why you put this in the Script Submissions section, but whatever, moving to Support.

You'll need to be more specific than that in order for us to help you. To start, which battle system script are you trying to add? A link to said script would be useful too.
