Don't understand error message ?

Bug 6484.sm (10 KiB) downloaded 43 time(s).

... not a bug wrt the construction.
Simply, it creates "shadow in the context" past some of the Alvaro coolprop.
It works at top of the work sheet. Whatever: can't understand the error message.

Sorry Jean, I do not quite understand your point. The picture of regions with the error are out of the context. What was the value of object "f" and "g" prior the error messages? The same name "f" can have a variable "f" or a function "f(x)" and they can exist both. Maybe there might be a problem.

Radovan

Within the CoolProp context, f & g may have relationship with their respective

f(T,v) Helmholtz free energy equation,
g(T,p) Gibbs free energy equation

It works at top of the work sheet, but not within the context: shadow in the context.

Thanks Radovan.

Ah, now I see it...

seems related to the fact that the diff function is overridden in amid of the worksheet (see Ndiff, Nint collapsed area)... the unapply() function makes anything (even numbers) as functions, must be improved a little
