How can I link text in two GUI's?

I have a GUI about the character playing and It says the Name, Health and I want it to say the Side so either Good or Bad. How would I link an Intro GUI that makes the User choose which side he/she wants to be on and then show the chosen answer on the Character GUI?

If you used GUI buttons:

You could use a variable that you can access from where you will show the side on another GUI; such as a global variable, or using the same script for both GUIs.

You could use a BoolValue with true and false being the side they are on, or you could use a StringValue with the name of the side that they are on.

There is more ways that you could do this if you took how these would work and compared them to properties and objects accessible by both the Intro GUI and Character GUI.
