[Javascript] Newbie- Error Message??

Mon Mar 18 01:02:37 CST 2002

At the line 'var secCtr = theDate.Seconds();', I get the error message "Object does not support this property or method".  The code that contains it is used to flash a message in a TextBox.  When I replace the secCtr variable with theDate.Seconds() and use it in If statements, it works.  Some one please explain to me in simple terms why I'm getting the error message.  Here is the code:
