I set up a table in document 1 with one of the columns referring to a review date. In row 1 fir instance the review date was "Jan 2016". I then inserted a bookmark around this date (called ReviewDate). In document 2, I tried to use the link field command listed "Insert, Quick part, Field" and tried to follow the procedure for linking file, bookmark and auto update to give the date Jan 2016 in a cell within a table but kept getting the message "Error! not a valid link"
