Welcome! You’ve simply entered the wrong text for the type. It’s not “TextMeshProGUI”. It’s “TextMeshProUGUI”.
Also, for future reference you’ll want to make sure you use code tags for sharing code , as it’ll format the text and make it easier for the rest of us to read, which will make it easier for people to assist you. Also make sure you copy the exact and full error message from the console, as it points to directly where the issue is (saving us AND YOU from having to hunt it down). I can tell you didn’t copy it because your error message has typos in it.
Back to work!
