so is it adding a link? i didnt follow. after selecting hyperlink what must i do? i typed the ID of the other task into the adress field of hyperlink. it was 18. then i inserted a row above that task so now it is 19. but the 18 in the hyperlink didnt change. for example when you assign a predecessor of task #18 to a task, and then if that task later becomes 19, the predecessor now shows 19. is there a way to do this in other coumns or this hyperlink for informational purposes?
