Hi All,

I have a GUI, where I am to fetch values from another .m file depending on which choice they make in the popupmenu (different kind of ships). So far I get the correct values showed in the GUI window, but the data the program is parsing is not correct. I do not know where they are taken from, definately not my data.

So my question is, how do I assure, that the right values are taken from one .m file are parsed to the next one. Two bites of my script looks like this:

function popupmenu1_Callback(hObject, eventdata, handles) % hObject handle to popupmenu1 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA)

% Hints: contents = cellstr(get(hObject,'String')) returns popupmenu1 contents as cell array % contents{get(hObject,'Value')} returns selected item from popupmenu1

 switch get(handles.popupmenu1,'Value')
     case 1 %Container ship
        number = 1;
     case 2 %Bulk Carrier
         number = 2;
     case 3 %ULCC
         number = 3;
     case 4 %Ro Ro
         number = 4;
     case 5 %Cruise liner
         number = 5;
     case 6 %Container feeder
         number = 6;
     case 7 %Chemical tanker
      number= 7;
     otherwise
 end
 %handles.number = number;
[Lpp,B,D,T,Disp,Loa,AeA0,Dmax,z] = Shipdata_module(number);
set(handles.Lpp, 'String',Lpp);
set(handles.B, 'String',B);
set(handles.D, 'String',D);
set(handles.T, 'String',T);
set(handles.Disp, 'String',Disp);
set(handles.Loa, 'String',Loa);
set(handles.AeA0, 'String',AeA0);
set(handles.Dmax, 'String',Dmax);
set(handles.z, 'String',z);

And the other one sending the vaariables away:

function loadship_Callback(hObject, eventdata, handles) % hObject handle to loadship (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA)

assignin('base','Lpp',handles.Lpp); assignin('base','B',handles.B); assignin('base','D',handles.D); assignin('base','T',handles.T); assignin('base','Disp',handles.Disp); assignin('base','Loa',handles.Loa); assignin('base','AeA0',handles.AeA0); assignin('base','Dmax',handles.Dmax); assignin('base','z',handles.z);

[Vkin,g] = Userinputmodule(handles.Lpp,handles.B,handles.D,handles.T,handles.Vsin,handles.Disp,handles.Loa,handles.z,handles.AeA0,handles.Dmax,handles.route); guidata(hObject, handles); initialize_gui(gcbf, handles, true);

I hope someone can direct me :)
