Hi. Please help. I have created a form for a bus company. I have added 'from' combo box, where list of cities from which the bus goes, and then created 'to' combo box, which list the cities where the bus goes. I want 'to' combo box list only those 'to' routes which are defined in my table. I have used the following article but it didn't work http://office.microsoft.com/en-gb/ac...001173058.aspx . That is for instance I have bus routes from NY to Boston, but not to Miami. So, when I choose NY as 'from' destination, 'to' combo box will list only Boston and not Miami. Thanks in advance
