How to display text in Unity game - unity3d

Question

I inherited by my ex collegue a Unity game. Now I need to implement this behaviour. The game consist in a car drive by user using Logitech steering.
Now I need to show a Text every X minute in a part of the screen like "What level of anxiety do you have ? " Ad the user should to set a value from 0 to 9 using the Logitech steering but I really don't know where to start.
This is my manager class:

When "SetRandomDotPosition" method is called, in my scene I can display in a random position of the screen the RedDot (that is a simple image with a red dot), but I m not able to display my textAnsia2. How can I fixed it ?

I hope this will help you to get started :

I hope that in the video i covered every step that i've made.
Edit: The only thing is for you to do is to make the input of the Wheel to work on the slider. Try to make a simple script: when the text is enabled then the input from a joystick to work on that . When is disabled switch it back for his purpose .
