/******************************
NOTE: abbarant behavior can be caused by lack of a properly named id in the label.
if the js tries to set the property for the label to red and this label doesn't exist
the function quits and error checking is lost.

NOTE: This is the second time I've come to this file to note this behavior 6/16/08.
This needs to be fixed. The simple fix is to do if(document.getElementById(label)) or some other such
integrity check.
