SQL Database connector Issues

So I’m trying to get data from my external database to display dynamically, so I want the users “steamhex”(bubble) to match the external databases “identifier”(mysql) then pull data from the array such as “bank”(msql) and display it in my bubble page. It never dispalys anything…

I removed the @ and now the data displays but I still can’t seem to filter the data to only show one set specific to the filter ie steamhex=identifier
