RE: Broken Links
Hello Mark
Thank you for your question and welcome to the forum.
You can fix a link if you know what has caused it to break - e.g. the source file has been renamed, or moved to a different location.
If you go to the Data ribbon and click the Edit Links button, then use Change Source to navigate to and select the file you wish to re-establish the link with, this will fix the broken link.
Kind regards
Amanda
