This paragraph should answer your questions.

Thanks so much!!! I thought this challlenge was relatively easy, but it would throw up errors every time until I saw your comment!! Lifesaver!

1. always use the spoiler flag when posting code / solutions (I have added the flag to your comment) otherwise anyone can see it
2. I suggest you make a habit of reading your error feeback very carefully:

should return "Odd" for odd positive numbers
Expected
    <string>: odd
to equal
    <string>: Odd

Bugged user.

And who says they are? Can you explain what the problem is exactly?

Your solution causes following error:

Incorrect answer for number=-21
Expected: equal to "Odd"
Actual: "Even"

Your solution incorrectly returns "Even" for n=-21.

Bugged kata, -21 and -977 are not even.

Found it in the below comments

Maybe mb but I didn't read the solution setup, as it was written awkwardly.
No intent updating the Details?
