Unfortunately you are not in a club therefor we cannot accept your entry for the contest.
It is good that you enter contests as it is a great way to grow your account so that you can enter a club. Of importance is the following;

1. Make sure you complete the achievement challenges
2. Add tags to your post and use #newcomer as one of the tags

I am going to share some links of posts that will help you with your future posts.
