I got two "Unterminated string constant" errors:
On line 107, there is a newline following the initial quote for the string " seconds left until ":

document.countdownnsmain.document.countdownnssub.document.write(opentags+dday+ " days, "+dhour+" hours, "+dmin+" minutes, and "+dsec+" 
seconds left until "+occasion+closetags)

and at line 145 , there a a couple of newlines embedded in the string "window.open('http://...,left=110')":

  "window.open('http://pub17.bravenet.com/guestmap/show.php?usernum=1409424668&lightmap=0&icons=0&&entrylist=0&zoom=0&welcome=1',
'bnetguestmap','toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=0,resizable=0,width=720,
height=470,top=110,left=110')">&rsaquo; Guest Map </a>
