It’s just not working
I think it might be because you have two dots rather than one.
EDIT: I forgot what the dots are called lol.
Don’t judge me, ok? I don’t pay attention to small identifiers when scripting.
The line in the question:
Clone1.Namey.Text = "<font color="rgb(255,255,255)">[Developer]</font> "..Clone1.Namey.Text
Since you had double quotes within the string, you accidentally close it at = and reopen it at >. You need to escape the double quotes there like so:
Clone1.Namey.Text = "<font color=\"rgb(255,255,255)\">[Developer]</font> "..Clone1.Namey.Text
use [[ ]] to cover the whole thing, because your string just completely stops
