Hi, thank you very much for all your help. I will be working on the App this weekend since my job keeps me very busy and it is difficult for me to work on the App during week days. I just began experimenting with the project you sent and will try to incorporate it into the App.
Regarding the DB showing some corrupted posts that is because I entered those manually and they were not generated by the App since I was experimenting. There are a couple of European posts (UK and Spain) those also were also entered manually. I will also work on the issue with the Square Bracket after the Brand variable and the message “Cannot parse text arguments to list from csv table as a CSV formatted table”.
Anyway I will try to adapt your routine to get the results I want according to the following behavior:
Once clicking on the “I Need Petrol or I Need Diesel” button a list of the available stations is displayed through the corresponding ListView as shown.
Every post has a call to action inviting the user to select her / his choice. Then when selecting any post Google Maps opens up showing the route to the selected station.
Basically that is the logic I am trying to get. I will try to implement what you sent and let you know how it comes up.
