Accessing Individual Collection Elements

Hello, I’m currently working with a database collection using Wix’s code. Previously, I displayed information using a table that accessed the entire database itself, and using a search function that limited the data. I was able to display items from a certain category using those parameters I put in.
Right now, however, I am trying to put INDIVIDUAL data points and information into text labels using code, but I’m having difficulty. I am unable to work with the database collection in this way, i.e. accessing individual items and information pieces, but I think that I do this by looking at individual indexed elements. I am just not sure of the syntax. Can you help me access these individual collection elements? Thanks.

Please explain in more detail what you are trying to do.
