Thanks for getting back to me Chris. I didn't have any luck at first so i went looking for some kind of work around. After many hours of searching, I found what looks to be an easy fix. I'll let you know how I go.
I came across a similar problem when setting up puzzles in my game and i think the integration of a crafting system or at least the ability to combine multiple items would be a great addition to the already great asset that is Adventure Creator.
