Hello,
I am writing a code that goes as follows:
% --- Executes during object creation, after setting all properties.
function popupmenu1_CreateFcn(hObject, eventdata, handles)
% hObject handle to popupmenu1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles empty - handles not created until after all CreateFcns called
% Hint: popupmenu controls usually have a white background on Windows.
% See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor','white');
end
% --- 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)
Addition=inputdlg('Please Add New Client Name');
With this code, when the user clicks the push button an input dialog box will pop up for them to add a new client name. I then want to take this client name and add it as a new variable in the previously created pop-up menu. Is this possible?

current_entries = cellstr(get(handles.popupmenu1, 'String'));
current_entries{end+1} = Addition;
set(handles.popupmenu1, 'String', current_entries);

I'm not sure what you mean by 'add it as a new variable in the previously created pop-up menu'. If you want to set the default string that is shown in the dialog box use answer=inputdlg(prompt,dlg_title,num_lines,defAns) and set defAns to your last answer.
