How to take additional inputs from user after selecting an option from popup menu?

Hello All, I am working in building a GUI from my script. Now I am at the point where I need guidance in popup menu of the GUI.

I have 4 different values for popup menu and I am trying to get additional inputs from user.

So suppose the values in my popup menu are:

--Select a combination--
Combination1
Combination2
Combination3

So now what I want is, initially the GUI will show --Select a combination-- as popup value. Now when user clicks on the drop down and select combination 1, a new window should open to get additional inputs required. Like wise if he selects combination2 while combination1 window is open, the combination1 window should close and combination2 window should open.

I hope I have explained it correctly.

selection = get(hObject, 'Value');
switch selection
  case 1: do_work_for_combination1(handles);
  case 2: do_work_for_combination2(handles);
  case 3: do_work_for_combination3(handles);
end

Hello, Thank you for the suggestions. I found this :http://in.mathworks.com/help/matlab/ref/inputdlg.html

I want to use this to get the additional inputs but I am not sure how to retrieve those inputs,

Here is my code:

selection = get(hObject, 'Value');
switch selection
    case 1
        h=msgbox('Please select the Combination');
    case 2
        te1=0;
    case 3
        te1=1;
        prompt = {'enter the radius of the sphere (mm)','enter the x coordinate of the sphere mid-point','enter the y coordinate of the sphere mid-point'};
        dlg_title = 'Sphere';
        num_lines = 1;
        defaultans = {'','0','0'};
        answer = inputdlg(prompt,dlg_title,num_lines,defaultans);

end

Now I want to retrieve the values given by users and assign them to the variables x,y & z.

Can you help me on how to get those values?
