Here is a doc page talking about the general process of writing component callbacks in appdesigner. In this particular section, there is an example dealing with a slider callback.

so what i basically want to do is when i push the start button, my script runs and i can change the value of N as i need.
while true
% code
% Slider value (N) varies when i change it
% code
end
I hope this clarifies the Situation a bit better.
Thanks in advance

Rather than changing the value of a fixed variable I would likely retrieve the Value property of the slider object whenever I need to use its value. This way I would be sure to always have the current value of the slider.

do i need to store the value of the Slider as a propertie in order to share within the code?
will this work ? (i'm new to designer..)
properties (Access = public)
Slider_CurrentValue % Description
end
function SliderValueChanging(app, event)
Slider_CurrentValue = event.Value;
end
% Buttonpushed_to_start
while true
m=x*(app.Slider_currentValue);
%code...
end
