Linking data to charts in Powerpoint

[NMJones]

I have a powerpoint presentation with ~80 charts that link to data on excel worksheets. I created the links by copying the cells in excel and by opening the chart datasheet in Powerpoint and entering Edit / Paste link. The links are set to automatically update - but they don't - I have to click on each one of them and open the datasheet for them to update.

From what I've read on Microsoft Help the links should be updating. I'm I missing something? I know this is more of a Powerpoint question - but any help would be appreciated - too much clicking!
