hello all

I am working on a very complicated excel file which contains many links from
other files, which means if there is any changes in those files, the result
in my files will be changed co-ordinately, and I almost can not pay attention
to every one. it is very annoying. so I am very curious if there is any way
to alert me if the number has been changed. It means every time I open the
file, if there is any number has been changed, it will be highlighted
automatically.


many thanks
