CLEO Help Detecting the full name of type NR in chat

[Escalasion]

Hello! How could I make the script detect each player's full name? I know that variables like 0-31@v can hold up to 16 characters. I tried using a normal variable like 3@ with memory allocation on it to save the player's full name in the variable, but it doesn't work at all. What should I do? I really need the correct code to save a long name up to 24 characters long, until it stops at ":".
