Hi,

The problem is subtle.

Prime goes through the sheet first to evaluate global variables only designated with global equal sign.

Prime then goes through the file a second time from top to bottom left to right evaluating normal equal sign ":=".

z.min is only defined on the second pass so global definition cannot see zmin.

Solution is to define things with ":=" while working top to bottom, left to right.

For instance Kr is not defined before function cr(ze)

If it is necessary to use a globally defined function define all variables as parameters of the function.

Cheers

Terry
