How to change you to change YOU to the name the readers chose whenn YOU is talking

I am having trouble figuring out how to change YOU to the name the readers chose

this this the line of ode I need to edit

    YOU (talk_greet)
Hi I am [FIRSTNAME], This is the story of how I live with the Skorys

When the character talks it comes up as YOU and not the name the character chose

Please help

Go to characters, and and go to YOU.
It says:

Script name: YOU
Display name: YOU

change the Display name to FIRSTNAME

Then save : )

Thanks it really helped
