Sai,
You have to look at the project table in it there is start date's, I have copied the start date here, and if you do the same on your copy of the database and place it in the start date, it should activate the form and show you the Gantt Chart,
StartDate Field content = 2003/08/10
There is a reasonable amount of VBA code that makes this work, so I am not sure of your knowledge here and how you would then adapt it for your database?
