Dear Hans van der Meer,
Thank you for your sample code.
I learned how to pass the value of the variables.
BTW, if I change “orange” to “red” or “green”, it is working fine. I think that
“orange” is not the predefined color. There is no color “orange” in the
MetaFun manual either.
Thank you.
Best regards,
Dalyoung
