Say you have an external method, or a SQL Method that accepts a parameter. You want that parameter to be dynamic (possibly based on a field from a DB). How can you pass a dynamic parameter to a method from within DTML?
i.e.: <!--#in expr="getSpam(cost=<!--#var spamcost-->)"-->
What you've got is basically right, it's just a question of syntax. In general you can refer to variables defined in the REQUEST by name: <!--#in expr="getSpam(spamcost)"--> Sometimes there are problems with this, if for example you want access to special sequence-item variable. In these cases you can lookup variables in the namespace mapping object (whose unpronounceable name is written '_') like so: <!--#var expr="getSpam(_['spamcost'])"--> For an example of how to use this namespace feature to include random bits of content see: http://www.zope.org/Documentation/HowTo/RandomContent You should also check out the DTML Users Guide which spells out pretty well how to use DTML: http://www.digicool.com/site/Principia/DTML.html Hope this helps. And BTW, DTML *is* complex; your question is not stupid. -Amos
