[Zope] dtml-in syntax

[Kapil Thangavelu]

A couple of different solutions depending on exactly what you want to
do. 

if you're just trying to get the total length of the records returned by
wherever you could try.

<dtml-let x=whatever>

<dtml-var "_.len(x)">

</dtml-let>

or if you want the distinct values as well

<dtml-in whatever>
<dmtl-var sequence-item><dtml-var sequence-number>
</dtml-in>

a great reference is the Zope Quick Reference
at http://www.zope.org/Members/ZQR

Check out the dtml-in docs.
