toggle button callback did not function

function closepump_Callback(hObject)
%CLOSEPUMP Summary of this function goes here
%   Detailed explanation goes here
global GUI


if get(hObject,'value')==1 % button down
    set(hObject,'BackgroundColor',GUI.offcolor,... %yellow = pump running
        'string',[valves open]);
    
elseif get(hObject,'value')==0 %button up
    set(hObject,'BackgroundColor',GUI.menucolor,...
        'string',[valves close]);
else
    fprintf(2, 'callback object value was not 1 or 0, was %g\n', get(hObject,'Value'));

end

this is my callback of a togglebutton. However it said there are too many input arguments. How can I fix it?

Try this:

function closepump_Callback(hObject, eventdata, handles)

I suspect the last two inputs somehow got deleted by accident.

[Kuang-Yu WANG]

not this problem. But still thanks. I found out that is

'string',[valves close]

need to change to

'string','valves close'

No, that would not have made the difference for that error message. However, the missing input arguement locations would make a difference. See for example your July posting about this same software, in which you had coded

    function checkpump(hObject, ~, ~)

Notice three input arguement slots.
