really need help here. i am sure its simple please someone help.

Code for pushbutton:

function edit1_Callback(hObject, eventdata, handles)
% hObject    handle to edit1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hints: get(hObject,'String') returns contents of edit1 as text
%        str2double(get(hObject,'String')) returns contents of edit1 as a double


% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
set_param('mymodel','lock','edit1');



lock is the parameter in mymodel i want to change. edit1 is the the text field in my GUI.

ERROR:


??? Error using ==> GUI>pushbutton1_Callback at 104
block_diagram does not have a parameter named 'lock'.

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

Error in ==> GUI at 42
    gui_mainfcn(gui_State, varargin{:});

Error in ==> @(hObject,eventdata)GUI('pushbutton1_Callback',hObject,eventdata,guidata(hObject))



I have set the path correct and the parameter is a constant block called 'lock' in mymodel.

what is the problem

Dear Luke!

You did not specify where the problem occurs exactly.
Please try this:
  dbstop if all error
Then the debugger stops when a problem occures and you can inspect the variables in the command window to find the problem -- and hopefully its solution.

Kind regards, Jan
