[Zope] -1 != -1 ?

Hi, I'm a bit confused. I have a Website with a select field. You can choose numbers between 7 an -7 (<option value="-7">). If the number is positive everything is fine, but if it is negative Zope behaves strange. First I convert the string "-7" into an integer publishRange = int(publishRange) and then want to know whether it is positive or negative, but if publishRange < 0: doesn't react to it (if publishRange > 0: does, if publishRange is positive). What am I doing wrong. MfG Steffen -- Manche Maenner bemuehen sich ein ganzes Leben lang, das Wesen einer Frau zu verstehen.
