I am trying to update my static text with tag text105 on my gui according to the value selected from the list box. The code I have developed is below, but it failed to display the value. Kindly spot the error.
function listbox1_Callback(hObject, eventdata, handles)
a=get(handles.listbox1,'value')
if (a==Natural-Gas)
Cv=12500;
set(handles.text105,'string',Cv)
drawnow;
elseif (a==Propane-Butane)
Cv=11950;
set(handles.text105,'string',Cv)
drawnow;
elseif (a==Fuel-Oil)
Cv=9520;
set(handles.text105,'string',Cv)
drawnow;
elseif (a==Diesel)
Cv=1000;
set(handles.text105,'string',Cv)
drawnow;
elseif (a==Brown-Coal)
Cv=3500;
set(handles.text105,'string',Cv)
drawnow;
elseif (a==Woods)
Cv=2500;
set(handles.text105,'string',Cv)
drawnow;
elseif (a==Electricity)
Cv=860;
set(handles.text105,'string',Cv)
drawnow;
end
