Help with Cam.Start3d3d

Trying to make hovering text over an entity that shows its name. I am getting lua errors

Are you calling ENT:Draw from somewhere? Because you are not supposed to.

[Exho]

I am. I want it to draw the name of the entity over it when the player is a Traitor.

You aren't suppose to call ENT:Draw(). It does it on its own when there is an entity.
