I'm making a site that user enters the ORIGIN and DESTINATION and click submit. Then, it will show the time that takes from the ORIGIN to DESTINATION that user just fill in and submit.
I have test the database like this:
ORIGIN - DESTINATION - Time
A - B - 1
A - C - 2
B - A - 2
B - C - 3
C - A - 2
C - B - 5
So how can I make the site with that features above? Thank You!
PS. I've tried to make it but it doesn't work. The Drop Down isn't working
