I have linked a couple excel tables into a power point that I want to update in excel and then have the corresponding updates occur in powerpoint.

I used Paste Special>Paste Link> Microsoft Excel 97-2003 Worksheet Object

When i change it on the excel document it works. Here is where I am having the issue. I need it to update on a continuous powerpoint loop that runs all day in our office and never stops. Is this possible or am I going to have to update excel document, stop the presentation, update all the links by right clicking and then restart the presentation?

Thanks for the input/help!
