Edit text as input in GUI

Hello,
I have a GUI (created in GUIDE), and I want to be able to have a edit text that I assign values to it and when I hit on other buttons, that value will be used. The problem is that it's not actually a number, but a set of numbers, i.e:
1:2:33
or even multiple inputs such as:
1:5,22:52, 66:68 etc
I have tried the below code but didn't work
function edit3_Callback(hObject, eventdata, handles)
% hObject handle to edit3 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: get(hObject,'String') returns contents of edit3 as text
% str2double(get(hObject,'String')) returns contents of edit3 as a
double
handles.back= str2double(get(hObject,'String'))
any good suggestions? TYIA

Don't do anything in the edit field callback. Do everything in the button callbacks where you want to use the edit field. For example in the callback for button1:
editText = get(handles.edit3,'String');
% Now parse it with sscanf(), allwords, or whatever.
myNumberArray = ......% whatever...
Find allwords here: allwords()

I used the eval function after all and works perfectly...
