Combine Export and Local variables?

[roadrunner]

A couple things i noticed:

First,
I think this line: Cld2:=CAS("sqrt(Cld1)");
Should be this: Cld2:=CAS("sqrt(Cl1d)");

Second,
In this line: LOCAL Cx1,Cl1,Ql1,Clk1,Qvk1,Cv1,SCx1;

you declare variable Ql1 but I didn't see anywhere that is was assigned a value. It looks like you started to with this: //////Q= CL, but remed it out. When you declare a variable they start out at zero so at this line:

Cl1:=Ql1*Vf1(1,1);

Cl1 = 0*Vf1(1,1) which is zero. That causes this line:

EDITMAT(Cl1,"Cl");

to flag an error. EDITMAT only works on matrix variables.
