I completed all modules and now competeing for super badge in reports and dashboards i am getting this query can anyone help me out ? 

The first challangeof this Superbadge seems to be problematic, showing the following message:
Challenge Not yet complete... here's what's wrong:
We could not find enough records in the 'Contacts' object. There should be at least 100 from the import.
What is interesting is that everything seems complete to me! I have inserted 100 contacts and 100 accounts, and of course all other items (Opportunities and Contact Hobbies).

Any idea why I see this error message?

please correct this code and help me earn this badge ...have completed all tasks ..except this one ....

IF( MONTH( NOW() ) = 12,
  DATE( YEAR( NOW() ), 12, 31 ),
  DATE( YEAR( NOW() ), MONTH( NOW() ) + 1, 1) - 1
