I need to control the visibility of a form object (specifically a 'submit button' inside a td) using a timer. Basically, I'd like to show the user a flash video and then make a form button visible only after the video is finished playing for 30 seconds.

So I'm wondering if there is a similar script that controls the visibility of a column (td) based on time, like counting down from 30 to 1.

Thanks for any assistance!
