Passing multiple variables from page to page via URL isn't working

I’ve tried searching and found a lot of questions and suggestions that don’t work.

This is my URL:

https://mysite.com/playerinfo/?nameFull=Evan&team=16

With just “nameFull” it works. When I add “team” it sends me to a 404 page. There is a suggestion to add this to the config.php page:
unset($_GET[‘team’]);

…but while that enables “nameFull” to be recognized, it doesn’t recognize “team”. I think I get what the ‘unset’ does, but I wanted to try it. I need both to work.

Using:
$team = $_GET[‘team’];
echo $team;

$team is basically null.
