Copied working jass not working in my map,help

[Stefanman]

So,i was searching for Rocket Barrage spell and found someone post code on it on this forums.The spell works good on the example that guy uploaded.
Now,i copy the jass,and the dummy and spell from example to my map.
I didn't change jass code at all,only where he said to input your dummy ID and spell ID,which i did. And so the jass is giving the error which is not in code..
I have no knowledge of jass,althou i can understand a bit,but i think that is not problem here :s Hope that things i said made sense.If you download map look for Rocket Barrage spell and 'Bo T' unit.Thanks http://www.2shared.com/file/ibVPAN51/test_2.html

I dont know, probably variables are problem. Maybe it is in vjass, what can be additional problem.
