Create the “customers” table from Sales database

After the lesson (Creating a Table). I tried attempting the exercise, which is; Create the “customers” table in the “sales” database. Let it contain the following 5 columns: customer_id, first_name, last_name, email_address, and number_of_complaints. Let the data types of customer_id and number_of_complaints be integer, while the data types of all other columns be VARCHAR of 255.  But it didn't pull through when I input the execute icon, showing me an error message. This is my attempt     USE sales; CREATE TABLE customers, ( customers_Id INT, first_name VARCHAR(255) last_name VARCHAR(255) email_address VARCHAR(255) number_of_complaints INT );   Then I press execute. But its giving me an error message. Please assist me. What am I doing wrong
