Gui that opens another gui. Need to send variables from one gui to other gui and vice versa

Right now I have a Main Gui and a Sub Gui. I need two variables from the main gui to copy to my sub gui, and two variables from my sub gui to copy to my main gui. The Main gui has a button called "calculator' that opens my sub gui. The two guis have separate scripts. I have looked at using guidata and sendappdata but I can't seem to find how to tell matlab the variable is in a different script.
I want to send variable a and variable b from my Main GUI to my Sub gui (when I press pushbutton'Calculator') and then variable c and variable d from my Sub GUI to my Main GUI when I press the pushbutton 'OK' in the sub gui. variables a and b are from listboxes in Main gui. variables c and d are from editText boxes in sub gui.
The Main gui stays open when I open the sub gui.
I am not sure what code to include to help with this question, so if you need to see some of my code please ask and tell me what part would be helpful.

Here is an example. Adapt it to your needs...
function [] = gui_passdata()
% Pass data back and forth...
S.fh = figure('units','pixels',...
'position',[500 500 200 130],...
'menubar','none',...
'numbertitle','off',...
'name','gui_passdata',...
'resize','off');
S.ed = uicontrol('style','edit',...
'units','pix',...
'position',[10 60 180 60],...
'string','Enter Data, push button.');
S.pb = uicontrol('style','pushbutton',...
'units','pix',...
'position',[10 20 180 30],...
'string','Push to Get Data',...
'callback',{@pb_call,S});
guidata(S.fh,S);
uicontrol(S.ed)
function [] = pb_call(varargin)
% Callback for GUI_24 pushbutton.
S = guidata(gcbf); % Get the structure.
set(0,'userdata',S); % Save it in the root.
f = make_subgui;
% If user closes gui_passdata, close new one as well because it will
% error when it tries to execute the callback otherwise.
set(S.fh,'deletefcn',{@fig_delet,f})
function [] = fig_delet(varargin)
% Executes when user closes gui_passdata.
try
delete(varargin{3})
catch
% Do nothing.
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%SubGUI stuff...
function [f] = make_subgui()
f = figure('units','pixels',...
'menubar','none',...
'position',[750 510 200 100]); % Create a new GUI.
E = uicontrol('style','edit',...
'units','pixels',...
'position',[10 20 180 60],...
'string','Type something, press return.',...
'foregroundcolor','r',...
'callback',{@E_call});
pause(1.25)
S = get(0,'userdata');
str = get(S.ed,'string');
set(E,'string',str,'foregroundcolor','k')
uicontrol(E)
function [] = E_call(varargin)
% Callback for secondary GUI editbox.
S = get(0,'userdata');
set(S.ed,'string',get(gcbo,'string')) % Set gui_passdata editbox string.
close(gcbf) % Close SubGUI.

To get you started.
To call a second GUI from the first, just call it's name subgui.m is the name of the subgui, in maingui.m
subgui

So you want to set(handles.edit1,'string',num2str(c))
%example edit1 is name of edit box, c is the variable you pulled from appdata.
?
