Resolved Error parsing format string: Could not evaluate the selector "teamName" at 12

I am trying to use the Smart String and it is not going so well.

So basically I have a small sentence to display with the name of a team and in the Preview it works fine



But when I run the game and try it out, this error shows up and nothing is displayed.



I tried it without the Smart String option and it worked fine.

Am I doing something wrong?

 

I noticed that the error was on the script that I made and the text wasn't active, my fault.
