Thank you again, we might almost be there but not yet.
If I use your code the towns are doubled again in the results, so it takes in the IDs, renames it to the town name and outputs this info twice. If I remove part of the code it works in a way that the town names are shown only once but.. there is a huge amount of blank spaces above the names (I figured out these are the IDs of the other ones) and no results are found for the towns, I have attached a screenshot for you to see, since I cannot leave this on the live environment. As you can see, the towns are shown once and on alfabetical order, which is exactly what we need, but no results.
