Here is what I need to do:
A) Field to populate with current vehicle selected (with the daily rental price value)
B) Pickup and drop off date pickers
C) Field to populate the number of days from the picker (I found the thread for this solution)
D) Field to show total price from line A x C
E) Pay total with third party gateway
Some of these may be basic, but I haven't found many how to's for this software. Thanks in advance for any help!
