How can I allow clients switch locations and destination with a button?

Hi,

My form has location and destination fields that the clients fill, and they need a button to flip between the entries (as in google maps routing).

To make matters a bit more interesting, i'm using a combination of  2 fields for each: a radio button list for their common destinations (neccesary since 99% of rides use one of them) and a Geocomplete widget for entering other addresses.

I've tried using the conditionals but i'm unsure of how to preserve the data before it is overwritten by the "copy to field".

Are you trying to swap entries between widgets? It seems to be not possible, I have tried it. The conditional logic won't work if you are targeting the same fields. I tried a textbox to no avail. 

A workaround would be to ask the user to determine their locations. Maybe, adopt the radio button fields method. 

My users will enter location/destination once, then they have an option to enter another order when they finish (using the thank you page -> prepopulate link). A lot of them will enter multiple orders that way, several days in advance.

I guess it is possible to just have another link for the return trip, changing the prepopulated fields accordingly - however that requires them to actually notice the 2 different links and use them correctly, with no option to change their minds or correct their mistake other than manually re-editing the form fields. 

I would REALLY like to avoid that - people will undoubtly make many mistakes that way, and I don't want to waste the time and resources to manually check each order...

If the purpose is just to keep the data then how about enabling the Auto Fill in the form?

I'm sorry, but I find no option to swap both entries in the form other than asking users to do it manually. Users can just submit a new entry if they wish to return to a different location. 

That's unfortuante. People are used to a flip button, like in most websites.

As for AutoFill, since these are recurring clients there might be issues i'm trying to avoid. 

AutoFill option is actually good for recurring clients if they are re-entering the same data in most of the fields in the form. We have Save data and Continue later option as well that could work for you.
