How to adjust codes so that appdesigner's slider and spinner value changes effect each other?

Hi everyone,

I put both slider and spinner in my app, so user can play with both. My codes allow user to play with slider and instantly updates the figure and the spinner value without pushing the "Run" button.

However it would be better if user is able to change the Mu by adjusting spinner too. So instantly the figure and the slider values changes accordingly too.

How do i do that? See below my app GUI.

Thanks,
