update links excel 2007
 

In excel 2003, when opening a workbook the following prompt comes up- "this
workbook contains links to other data sources... update, don't update,help".

I have saved the previous workbook in excel2007 and I don't get the same
message when I open the file. I need to update the links and would like to
know how to do this in excel 2007? Thanks for your assistance.
