I have a uitable that I want to be able to select a cell with a mouse, and the value in that cell be put in an edit box. Under the CellSelectionCallback, I have the following code.

However, it attempts to run (and crash) when the contents of the uitable change. How can I only implement this when the mouse selects that cell?

function uitable1_CellSelectionCallback(hObject, eventdata, handles)
% hObject    handle to uitable1 (see GCBO)
% eventdata  structure with the following fields (see MATLAB.UI.CONTROL.TABLE)
%  Indices: row and column indices of the cell(s) currently selecteds
% handles    structure with handles and user data (see GUIDATA)
%handles=guidata(source);
handles.currentCell=eventdata.Indices;
guidata(gcf,handles);
handles=guidata(gcf);
Indices=handles.currentCell;
data=get(handles.uitable1,'Data');
data=data(Indices(1),Indices(2));
set(handles.editNum,'String', data);

Thankyou Geoff, I've included another check before executing this:

if ~isempty(eventdata.Indices)&&~isempty(data)

Thankyou Geoff for the help, I've included another check before executing this:

if ~isempty(eventdata.Indices)&&~isempty(data)
if ~isempty(eventdata.Indices)
    handles.currentCell=eventdata.Indices;
    guidata(hObject,handles);
    Indices=handles.currentCell;
    data=get(handles.uitable1,'Data');
    data=data(Indices(1),Indices(2));
    set(handles.editNum,'String', data);
 end
