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
