Request-values encoded in the URL are strings by default..

either simply do "mypage?ddlb_val:int=2" in the url , or cast it to an
integer when you do the check ..

haven't done DTML in a year or two now (ZPT rule!), so i cannot remember if you
need to do the weird namespace-twiddling-thing for that , but it probably looks
somewhat like this :

<dtml-if expr="id == _.int(ddlb_val)">
