i want to use toggle with checkboxes that can control the buttons as for buttons can be push at the same time. however what i do can only move one button. please help.

toggleforall = uicontrol('Style','Togglebutton',...
  'String','Pumping Stop',...
  'Units','Normalized',...
  'BackgroundColor',GUI.menucolor,...
  'Position',[.58 .80 .05 .04],'Tag','tbfa','callback',@pumpcontrol);  
 checkbox1=(f,'Style','checkbox','UserData','Pump1',...
    'Units','Normalized','Value',0,...
    'Position',[.73 .37 .02 .02]); 
 checkbox2=(f,'Style','checkbox','UserData','Pump2',...
    'Units','Normalized','Value',0,...
    'Position',[.74 .37 .02 .02]); 
 slider1=uicontrol(f,'Style','slider',...
    'Min',0,'Max',100,'Value', 0,...
    'SliderStep',[0.05 0.2],'Tag','slider1',...
    'Units','Normalized','Position',[.78 .66 .08 .04]);
  slider2=uicontrol(f,'Style','slider',...
    'Min',0,'Max',100,'Value', 0,...
    'SliderStep',[0.05 0.2],'Tag','slider2',...
    'Units','Normalized','Position',[.79 .66 .08 .04]);
   function pumpcontrol(hObject, eventdata, handles)
 val=get(hObject,'value');
check = get(hObject, 'UserData');
if check ~= 0
    if val==1 % button down
        set(hObject,'BackgroundColor',GUI.offcolor,... %yellow = pump running
            'string',[get(hObject, 'UserData') ' running'],'FontSize',10);
       if check == slider1
            GUI.p1Running = 1;
            p1.ts = 0;
            p1.num = str2num(get(textbox1,'String'));
            ps=get(GUI.button(check),'Max')-get(GUI.button(check),'value')+20;
            set(p1.t, 'Period', ps/1000); %the number can change pumping speed
            start(p1.t);
        elseif check == slider2
            check = slider2;
            GUI.p2Running = 1;
            p2.ts = 0;
            p2.num = str2num(get(GUI.button(check+1),'String'));
            ps=get(GUI.button(check),'Max')-get(GUI.button(check),'value')+20;
            set(p2.t, 'Period', ps/1000);
            start(p2.t);
  end

if check == slider1

is not going to work. I am assuming your function is a nested function, although it is impossible to tell from the code you posted. If it isn't then slider1 is not in scope in the function pumpcontrol.

Mostly though slider1 is a uicontrol, check is a boolean. why are you trying to compare them for equality?
