Custom field in searches

Hi all

I have created some queries that I have added to a dashboard. Although I
can edit the columns that are displayed I can’t get changes to stick. I
have a custom field that I want displayed on the results of the search
saved in the dashboard but every time I go back to the results it has
dissapeared. How can I make custom field dispaly every time without
having to modify “Dispaly Columns”?

Many thanks, Jim
