Balancing Equations: Carbon Disulfide and Ammonia Reaction

[lakersfan]

I can't seem to figure out a problem for my a/p chemistry summer assignment review. If you could help me that would be great.

The problem is: Carbon disulfide liquid reacts with ammonia gas to produce hydrogen sulfide gas and solid ammonium thiocuanate.

This is what my answer was but it is wrong and unbalanced.
C2S + NH3 = H2S + NH4NCS

Carbon disulfide, sounds as CS₂, not C₂S...
