any ideas
decided to try to build it and it gave me this warning
Assets/Scripts/Inventory.js(62,56): BCW0028: WARNING: Implicit downcast from 'UnityEngine.Component[]' to 'UnityEngine.ParticleEmitter[]'.
One idea: hit the 'edit' link under your question, select the code parts, hit the 010/101 button above the text area, to format your code.
fireEmitters = campfire.GetComponentsInChildren(ParticleEmitter); is line 62
var fireEmitters : ParticleEmitter[];
var fireEmitters : Component[];
I'm not 100% sure, but try:
fireEmitters = campfire.GetComponentsInChildren(ParticleEmitter) as ParticleEmitter[];
This looks suspect:
fireEmitters = campfire.gameObject.GetComponentsInChildren(ParticleEmitter)
campfire is already a GameObject, so you should omit the .gameObject part of that line.
Which is line 62? It looks pretty ok. Sometimes putting 'as ParticleEmitter[]' after the GetComponents... call helps.

thats what i get for putting in 'fireEmitters = campfire.GetComponentsInChildren as ParticleEmitter[];'
