Hello,
This is the exact script I'm running in Matlab. I can't get the variable defined in the save callback to be recognised in the load callback. Any idea what's going wrong with it?

Any clarification would be great.

function init(hObject, eventdata, handles)
handles.fig = figure('units','pixels',...
'position',[220 150 400 290],...
'resize','off',...
'name','Two Body Problem',...
'numbertitle','off',...
'color', [0.925,0.914,0.847],...
'menubar','none');

handles.savetext = uicontrol('style','text',...
'position',[10 200 110 15],...
'string','Enter a Number',...
'visible','on',...
'HorizontalAlignment','left');

handles.saveedit = uicontrol('style','edit',...
'position',[90 195 110 30],...
'backgroundcolor','white',...
'enable','on',...
'visible','on');

handles.savepushbutton = uicontrol('style','pushbutton',...
'position',[205 190 110 40],...
'string','Click to Save',...
'visible','on',...
'HorizontalAlignment','left');

handles.loadpushbutton = uicontrol('style','pushbutton',...
'position',[10 100 110 40],...
'string','Click to Load',...
'visible','on',...
'HorizontalAlignment','left');

handles.loadtext = uicontrol('style','text',...
'position',[125 110 110 15],...
'string','Value Entered',...
'visible','on',...
'HorizontalAlignment','left');

set(handles.savepushbutton,'callback',{@save_callback, handles});
set(handles.loadpushbutton, 'callback',{@load_callback, handles});



end

function save_callback(hObject, eventdata, handles)
number=str2num(get(handles.saveedit,'string'));

handles.number=number
guidata(hObject, handles)

msgbox('Variable saved','Saved');

end


function load_callback(hObject, eventdata, handles)
number=handles.number
set(handles.loadtext,'string',num2str(handles.number));

end
