SELECT has invalid inputs

[NewGuy]

I can not get the Select function to work. I have tried examples on YouTube even copying their example exactly as they have it, same result of Select has invalid inputs. This is my expression I am trying to fix. 

Any(Select(Parts[Description],[_thisrow],[Item Number]=[Item Number]))

Difficult to say what you are trying to do, but at least you should use a dot instead of a comma after the [_THISROW].
