Not enough Input Arguments

Im having problem with a script. Im trying to create a function that handles differents inputs in a GUI, convert those value, and display the result. The problem is that the script is not running the get(handles lines when its under the created function and is display the following error:

Not enough input arguments.

Error in EngineerTool1>ETConverterLenght (line 72)
LC_value1 = str2num(get(handles.LCinput,'String'));

Error in EngineerTool1>LCinput_Callback (line 134)
ETConverterLenght;

Error in gui_mainfcn (line 95)
        feval(varargin{:});

Error in EngineerTool1 (line 16)
    gui_mainfcn(gui_State, varargin{:});

Here is the code

     function LCinput_Callback(hObject, eventdata, handles)
    ETConverterLenght;

     function ETConverterLenght(handles)
    LC_value1 = str2num(get(handles.LCinput,'String'));

The script run just fine when it is beside the previous created function LCinput_Callback, the problem is that i cant create a function that does the same thing, and i dont know why.

Change your line

      ETConverterLenght;

to

      ETConverterLenght(handles);

Note: you have used "Lenght", but most people would use "Length"

It did work. Thank you so much.

The function ETConverterLenght isn't being passed an argument in the code for this callback:

      function LCinput_Callback(hObject, eventdata, handles)
    ETConverterLenght;

Maybe you meant to have,

        function LCinput_Callback(hObject, eventdata, handles)
         ETConverterLenght(handles);
