Precipitation Reactions

Write a molecular equation for the precipitation reaction that occurs (if any) when the following solutions are mixed. If no reaction occurs, write NO REACTION. Express your answer as a chemical equation. Identify all of the phases in your answer.

cesium chloride and calcium sulfide

I went through the solubility rules and balanced the resulting equation and this is what I came up with:

2CsCl(aq) + CaS(aq) --> Cs_2S(s) + CaCl_2(aq)

I inputted this into the system and it said I am incorrect. Can someone please check my work and if it is indeed incorrect, then explain HOW to reach the correct solution (I don't need the answer).
