I understand how I can use the cascading dropdown to auto populate fields based on the parent drop down. Here is my dilemma.
I want to allow the user to use their assigned permit ID number to populate the remaining fields. (year make model and color of the car) if it exists in the permit database. I do not want to use a dropdown as I do not want to display a list of active permit numbers. How would I use a text field as the parent to populate the child boxes below? Also, how would I display an error message (maybe "This permit is not registered in the system. You must use a valid permit number to proceed") if the permit does not exist in the permit table?
