I cannot make a worksheet function as it should in MapleNet 11. It contains a graph and a slider to adjust the graph. It looks fine, but when I try to read the value of the slider I get an error message "Error: ecslider17 not found". The worksheet works perfectly in "offline Maple".

Any suggestions how to fix this will be most welcome.

I am trying to find a way to programmatically start a Maple animation, specifically after a custom button has been pressed.

Equivalently, I would be happy with being able to pass an option do "display" function, so that when I use it to create an animation, it is running from the moment it appears on the screen.

Any hints will be greatly appreciated.
