Problem solving

I just started my first lesson. And i cant understand what the problem its showing

What's your cat's personality? Loving

they are saying “You should only have added one input element for your checkbox. Remove any extras.”
What extras???

If you have a question about a specific challenge as it relates to your written code for that challenge and need some help, click the Ask for Help button located on the challenge (it looks like a question mark). This button only appears if you have tried to submit an answer at least three times.

The Ask for Help button will create a new topic with all code you have written and include a link to the challenge also. You will still be able to ask any questions in the post before submitting it to the forum.

Thank you.

Hello,
extras mean additional input element that were not intended to be there, you must have added some by mistake so you should remove them
