Hi,
sure...you can run an update query on the values like you can for any other
data type.
A hyperlink can consist of three parts which are seperated by pound '#'
symbols. The first part is the display text, the second the link itself, and
the third could be a reference within the link destination.
So if you wanted to replace ALL hyperlinks with the same one then for
example you could use this in the update to area of your update query:
Left([HyperLinkField],Instr([HyperLinkField],"#")+1) &
http://www.msn.com
If you run the update query you would replace ALL links with msn.com. They
display text would stay the same.
HTH
Good luck
