Hi guys

I tried to run this sql statement below,
Code:
ALTER TABLE about ADD content MEDIUMTEXT(65,000);
under PHPMyAdmin, but it show some error message.
And the message was this,
Code:
#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.
