[Javascript] URGENT: Object required error in onClick event

[javascript@xxxxxxxxxx (Michael J. Mahony)]

The problem, though, is that even if I remove everything from the 
function but an alert, the function never runs.  The failure is at the 
onClick= line of the code.  I've even tried changing the name of the 
function and only including an alert inside the function to no avail...still 
gives me the object required error.
