```Let a function of six variable
AH[Ts_,Th_,Tr_,f_,w_,i_]:=(
Which[NumericQ[Ts]&&NumericQ[Th],tipo=1,
NumericQ[Ts]&&NumericQ[Tr],tipo=2,
NumericQ[Ts]&&NumericQ[f],tipo=3,
NumericQ[Ts]&&NumericQ[w],tipo=4,
NumericQ[Ts]&&NumericQ[i],tipo=5,
NumericQ[Th]&&NumericQ[Tr],tipo=6,
NumericQ[Th]&&NumericQ[f],tipo=7,
NumericQ[Th]&&NumericQ[w],tipo=8,
NumericQ[Th]&&NumericQ[i],tipo=9,
NumericQ[Tr]&&NumericQ[f],tipo=10,
NumericQ[Tr]&&NumericQ[w],tipo=11,
NumericQ[Tr]&&NumericQ[i],tipo=12,
NumericQ[f]&&NumericQ[w],tipo=13,
NumericQ[f]&&NumericQ[i],tipo=14,
NumericQ[w]&&NumericQ[i],tipo=15];
tipo)

In[77]:=AH[1,Th,Tr,f,4,i]
Out[77]=
4
Correct

In[78]:=AH[1,Th,Tr,f,w,5]
Out[78]=
4
Wrong

In[79]:=AH[Ts,Th,Tr,4,4,i]
Out[79]=
13
Correct

In[80]:=AH[Ts,Th,Tr,4,w,5]
Out[80]=
13
Wrong

I d'ont understand. Where is my error?
