Hello,

If you mean on the errors regarding "B92(u)" function and "fit" matrix with the error: "Variable and function names can't start with a number", this is due to the unsolved problem of summation in the B2(u) function. We have to define this function with the line environment, although it is a single line function (summation causes the problem). I really do not know why this problem appeared in the recent versions and when/if is going to be solved.

Regards,
Radovan

Thanks Radovan,

You have doctored/rescued the 3 work sheets.
Only B39(u) needs the local line definition.
The A's B's coefficients MUST NOT have local line definitions.
