I'm creating a course catalog form. I'd like to have the available Date/Time drop down list refresh based on what is selected in the Class drop down list. The available Dates/Times for each class is stored in a separate SQL table than where each user submits to when they click Enroll to sign up for the class, which is the Main Data Source. I've attached a screenshot of what I'd like it to look like. Any help would be greatly appreciated!
You can use filter condition to filter your data.
Attached a sample template with two drop downs, and added a SQL data connection.
Let me know if you run into issues.
Good Luck!
