I had done a typo in a textbox name “scoreText.text” and it showed as an error Natural.
But after I corrected the typo. It still showed as an error. Went back and forth to check the name and spelling.
All was correct. Even the case.
I ended up delete the typed one and started again. This time the suggestion came up with the textbox name And i selected it and all was checked out.
To me it looks like it did not check since the textbox was not put in by the autocomplete system.
Maybe this is a problem in Visual studio not Unity?
