MATLAB: Slider is still at min and not moving

slider step min max gui

Hi, this is part of my super simple slider, but it still not working…Slider is not moving. Thanks for help!!
function slider1_Callback(hObject, eventdata, handles)
  sliderMin = 1;
  sliderMax = 520; % this is variable
  sliderStep = [1, 1] / (sliderMax - sliderMin) % major and minor steps of 1
    set(handles.slider1, 'Min', sliderMin);
    set(handles.slider1, 'Max', sliderMax);
    set(handles.slider1, 'SliderStep', sliderStep);
    set(handles.slider1, 'Value', sliderMin); % set to beginning of sequence
    time=get(handles.slider1,'Value');
    set(handles.text1,'String',num2str(round(time)))
    guidata(hObject, handles);

Yeah, because you're setting the value equal to the min every time the user tried to slide it. Remove this line to fix it:
set(handles.slider1, 'Value', sliderMin); % set to beginning of sequence
