Moding the ME2 with the mod manager, request for code help, how do I add the "[myvariable]" -tags.

OK... like said in the topic title, I am trying to make my own modifications to the game, using the RoadCrewWorkers mod manager( http://social.bioware.com/project/1998/ ), but I ran to "ContentEditor.ini could not be found in original inis, skipping content..." error while trying to launch the game.

I know that this code line would work on already bite checked Coalesced.ini:

With target being the ###FILE:BIOWeapon.ini in manager, and I also know the other lines needing the + infront of them. 

[SFXGameContent_Inventory.SFXWeapon_myvariable]
Damage=(X=31.8,Y=31.8)
DamageAI=...

 So that turns to:

###FILE:BIOWeapon.ini
[SFXGameContent_Inventory.SFXWeapon_myvariable]
+Damage=(X=31.8,Y=31.8)
+DamageAI=...

So the question is, how do I add/tag the code line in the middle. so the editor adds it to the BIOWeapons.ini file with the rest of the file as it's not there yet.
