Why this query won't work?

Hi guys

I tried to run this sql statement below,

ALTER TABLE about ADD content MEDIUMTEXT(65,000);

under PHPMyAdmin, but it show some error message.
And the message was this,

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(65,000)' at line 1

So what I have done wrong here?

Thank you very much in advanced.

Shouldn't it be

 ALTER TABLE about ADD COLUMN content MEDIUMTEXT

Don't specify the length you want for the column:

ALTER TABLE about ADD content MEDIUMTEXT;

Edit: Dave beat me to it
