31. }
32. }

You've put your script on the gameObject that has the trigger collider on it? You're sure the player's collider gameObject has tag "Player"?

This is where you want to tease apart the potential causes and narrow it down. Add some Debug.Log statements to OnTriggerStay, to see what's within the trigger bounds. See if it's triggering at all. Then see what the Tag is of the thing that triggered it, etc. Maybe you're getting errors because uiElement is null? (It's not clear how you're assigning a value to uiElement.)
