[help] Expression selector to copy font style from another layer or other way
So I found a youtube tutorial about usingn expression selector,
https://www.youtube.com/watch?v=gsPgOQAlqeE&t=253s
and I was thinking of maybe changing a bit of the coding to make the selected characters to be BOLD but I'm getting this issue or maybe my code seems incorrect.
(Pic 1: is the original code which I got it from the youtuber)

So you could see that (fromtextlayer) , I'll just change the (fromtextlayer) text to a specific one, example "Mindse" and it would highlight the specific characters of (text1), and I was thinking of like changing that (text1) characters' style to bold.

(I really am new to coding and just learn it today just for a specific project and wanting to convert it to a .mogrt file to make things easier)
Sorry for my grammar. 😞
