I searched the entire worksheet for the line but didnt find it. Might there be anything else wrong?

Your answers are very helpful and inspire me!

I just moved the command "Do(%text_beta_radian=evalf(%text_beta_degress/180*Pi))" from  text_beta_radian to text_beta_degress, then I got the effect I wanted.
