[Zope] Quoting HTML

Hi; I have the following Python Script (*not* External Script): import string size = string.atoi(size)/1280 css = "<style type='text/css'>" css += ".headline { position: absolute; top: " + str(100*size) + "; left: " + str(150*size) + "; font-style: 800 " + str(40*size) + "px futura }" css += ".belowHeadline { position: absolute; top: " + str(150*size) + "; left: " + str(250*size) + "; font-style: italic " + str(25*size) + "px verdana }" css += "</style>" return css It isn't rendering properly because the brackets are being translated into ASCII. How do I prevent this? TIA, beno
