1. You create a trigger in the trigger editor, with the name of the thing you wanna copy.
2. Then you convert the trigger to "custom text" [Edit > Convert to custom text]
3. Delete every stuff inside the trigger-text-field and copy you trigger in.

Ahh yes I see it's vJass not Jass. Well for this you need some stuff:
1: Download the Jass NewGen Pack
http://www.wc3c.net/files.php?f=jassnewgenpack5d.zip
2: Download the newest JassHelper and update the execute files.

1. Download the zip data from point 2 and open it. In this file you see a folder named execute and in this there are some data.
2. Extract these files into you Jass NewGen Pack folder > jasshelper. he will ask for an overwrite and you say yes.
3: Try it again.

Well actually you just need to open your map with the NewGen WE (not the normal editor) then you can easy copy that spell in..
Well dude .. the normal editor (given by Blizzard, basically in Wacraft 3, not the NewGen Editor) will give always the error, when you try to save a vJass spell with it.
As I said, vJass doesn't exist in the normal editor, because it's custom made! So 1 + 1 = 2 > you have to use the NewGen Editor from now on and not the normal editor anymore.
Sure you can ... or at least why you cant?
Well can you give some exactly text of that error please? Else we can guessing years
