To be able to make a plot, you need an expression/function that will 
evaluate to a number.
First make sure that subst(B=0,Y(25)) and subst(B=0,Z(25)) give numbers 
and not expressions.
If you only have the definitions above, they will not evaluate to 
numerical values, because A(25), C(25) and
D(25) will not give numerical values.
