I need a little scripting help Energy Weapon ammo charger

[Deleted19691154User]

I want to add a Energy Weapon cell charger to my player home, it's intention is to swap out Draned Energy, ECP, and MFC cells and give the player the ammo in exchange. also I want to add a trap to catch the condition that the player has none of the appropriiate drained cells in their inventory and sends them to a Failed message. Also if possible I want to attach the need to supply a Fission Battery every time you use the "Charger"

 

Thanks for any help!! ;)
