javascript

I have a form that resides within a php function().  And, I would like to call 
a javascript function from an "onChange" event of a <selection> tag (a drop 
down list box).

Is there any problem with trying to call a javascript function from within a 
php function?  I tried putting the javascript function in the <head>.  But, 
that didn't work.

The form can be seen at:  http://www.crotchett.com/mcachess/register.php

The code in question is below.  I removed the redundant and irrelevant parts 
and noted where that was done:

Thanks,
