integrating two gui

hi i have some problem with matlab gui

i created gui with many text boxes that are used to get user datas like

name ,address etc and when the user pushes the push button it connects
tothe ms access database and loads the data in to the database.i have
two submenus in this gui called getdata and delete....

once i click getdata a new figure window will open(this is the second
gui i created with one text box and one push button)once the user click

the push button it, get the data entered by the user in the editbox(2nd
gui) and should connect to the databse.....but i am getting
error like

"Error in =3D=3D> untitled2>submit_Callback at 84
usrdata=3Dget(handles.dataretrieve,'string');

Error in =3D=3D> <a
href=3D"error:C:\MATLAB7\toolbox\matlab\uitools\gui_mainfcn.m,75,1">gui_mai=
nf=ADcn

at 75</a>
feval(varargin{:});

Error in =3D=3D> untitled2 at 44
gui_mainfcn(gui_State, varargin{:});

??? Error while evaluating uicontrol Callback."

but if run the second gui alone it works fine and i am able to retrieve

the datas from the database ..but if open the second gui through the
first gui and when i click the push button in the second gui it
shows the error shown above..i open the second gui by using openfig(my
second gui name) in the sub menu editor callback in the first gui
please help me out this.....

You're probably using GUIDE-generated-guis (or you prefer to use the
'handles' struct mechanism in your private code). I whole-heartedly
recommend avoiding this facility, specifically in multi-gui
scenarios. It makes heavy use of global data (setappdata, getappdata
etc), and practically begs for clashes between two simultaneous GUIS.

Have a peek at Doug's example at <http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=8616&objectType=FILE>
.

Sorry,

Ofek
