Hello Knowledgable ones,

I have an Excel 2003 worksheet that have external links in it to a website.
The links should be updating every 20 seconds. I want to be able to write a
formular in excel or somewthing that will tell me how long it has been since
the cell last updated as it is really imporatant that I am looking at current
info (and I have had problems with the data source going off line).

I would also love to be able to record what the data was before the info
updates as well so I can so what the movements have been.

Any idea???

Thanks

Jenny
