[Zope] variable length forms...

[Andy McKay]

<dtml-var "_['radiob'+_['sequence-item']]">

Will give you the item value. If you want to evaluate that value do:

<dtml-var "_[_['sequence-item']]">

or a little cleaner wrap it in a let so that

<dtml-let item=sequence-item>
<dtml-var "_[item]">
</dtml-let>
