Issue with Less Than sign. Reporting with SQL challenge Task 1 of 2.

The challenge:

https://teamtreehouse.com/library/reporting-with-sql/working-with-text/concatenating-text

In the library database there's a patrons table listing all the users of the library. The columns are id, first_name, last_name, address, email, library_id and zip_code. Generate a list of strings that are in the following format: Andrew Chalkley andrew@teamtreehouse.com. Concatenate the first name, last name and email address for all users. Alias it to to_field. This will be used in the "To" field in email marketing.

Query that I believe is the answer:

''' SELECT first_name|| " <"||email||">" AS "To" FROM patrons; '''

Results from above query:

To

Andrew

Dave

Alena

Michael

Bummer! Your query needs didn't retrieve the emails in the correct format.

Note: If a space is placed behind the less than sign the query retrieves the following:

''' SELECT first_name|| " < "||email||">" AS "To" FROM patrons '''

To

Andrew < andrew.chalkley@teamtreehouse.com>

Dave < dave.mcfarland@teamtreehouse.com>

Alena < alena.holligan@teamtreehouse.com>

Michael < michael.poley@teamtreehouse.com>

Bummer! Your query needs didn't retrieve the emails in the correct format.

Does anyone know what I am doing wrong? Or is this a bug?

Thanks in advance for your help.
