12,893 PointsHie, Tsitsi the syntax looks okay but on the challenge the name of the table is "movies" and not "movies_table" or "movies table" so you need to write it as:
ALTER TABLE movies ADD COLUMN genre VARCHAR(25);
and you will pass the challenge just fine.

3,173 PointsIs 'movies_table' the actual name of the table? What you have above is the correct syntax to add a column (without the word 'COLUMN').
ALTER TABLE 'table_name' ADD 'column_name' VARCHAR(25);
