[Zope] sum up values of two variables

[Tino Wildenhain]

Hi Marcus,

sure, you can do that. (put _.str() around the numerical return
value of len() )
But I dont think this is what you want here.
This way the link would contain:

<a href="BASE5"> or something.

May be, <a href="/<dtml-var 
expr="_.string.join(hello.getPhysicalPath(),'/')">/">   .. </a>

does what you want.
