Chemistry balancing help

Calcium Bicarbonate is reacted with hydrochloric acid to produce carbon dioxide, water and calcium chloride.
I am having trouble balancing the equation, do I have it correct? It won't balance!
_Ca(HCO3)2 + _HCl ---> _CO2 + _H2O
Would you help me with the equation, I think that it is good so far, could you get far enough for me to balance it, or tell me if it is ok so far?

I just notice, you didn't include calcium chloride in your equation.
Ca(HCO3)2 + HCl --------> CO2 + H2O + CaCl2
reactants/products
Ca=1/1
Cl=1/2
C=2/1
H=3/2
O=6/3

Balanced equation:
Ca(HCO3)2 + 2HCl --------> 2CO2 + 2H2O + CaCl2
reactants/products
Ca=1/1
Cl=2/2
C=2/2
H=4/4
O=6/6

Done!
