Automatic Links Cannot Be Updated

[JDB]

Hi,

I have a workbook that pulls data from several others. When I open this
workbook, I get the option to update which I select, I then get the message
'this workbook contains links that cannot be updated'. When I click edit
links to find the error, all the links are listed as ok?

Any idea what's going on at all? I'm stumped!

Regards,

Jason.
