Module in a package

When I use Module in a package Mathematica yields an error message and
I d'ont understand the reason.
 This is an example

Package Calor`Combustion`

CO2[c_,h_,o_]:=(
Module[{nci=(c*10/12),nhi=(h*10/2),noi=(o*10/32),a,b,c,d,e},
nc=nci;
nh=nhi-(2*noi);
no=nc+(nh/2);
2*no+5*nh
]


Notebook:

In[21]:=
CO2[60,35,5]
>From In[21]:=
\!\(\*FormBox[
  RowBox[{\(Module::"lvsym"\), \(\(:\)\(\ \)\), "\<\"Local variable \

\\!\\(TraditionalForm\\`\\({\\(\\(Calor`Combustion`Private`nci \

Out[21]=
\!\(TraditionalForm\`Module[{Calor`Combustion`Private`nci = \(60\
10\)\/12,
      Calor`Combustion`Private`nhi = \(35\ 10\)\/2,
      Calor`Combustion`Private`noi = \(5\ 10\)\/32,
      Calor`Combustion`Private`a, Calor`Combustion`Private`b, 60,
      Calor`Combustion`Private`d, Calor`Combustion`Private`e},
    Calor`Combustion`Private`nc = Calor`Combustion`Private`nci;
    Calor`Combustion`Private`nh =
      Calor`Combustion`Private`nhi - 2\ Calor`Combustion`Private`noi;
    Calor`Combustion`Private`no =
      Calor`Combustion`Private`nc + Calor`Combustion`Private`nh\/2;
    5\ Calor`Combustion`Private`nh + 2\ Calor`Combustion`Private`no]\)

Can you help me?. Thanks
