That's because you haven't quoted the 'tip == 1' bit.  If you want to use 
Python expressions, you have to quote them:

<dtml-if "tip == 1">

or, more explicitly (explicit is good):

<dtml-if expr="tip == 1">

By the way, without wanting to start *another* ZPT vs DTML war, I personally 
hate DTML and I advise anybody starting out with templating in Zope to head 
down the ZPT route instead of DTML.  IMO your life will be much easier in the 
long run :)
