I'm trying to create a query sort of like Yik Yak where I can see a query of messages within a certain location but the results are not displaying the data in the query whenever I post a message. I basically want the message I send to be shown in the query. I think I did my logic correctly in the code but I'm missing something here that could show the data in the query. I've been working on this problem for the last week and just this one fix could end this segment of my project. Can anyone help me with this?
