RE: [Zope] Building a list programmatically under DTML

I don't think you need an EM for that.

Just try <dtml-call "desc.append(_[Category])"> <dtml-call "desc_qty.append(qty)">

You don't need the idx var at all this way.

You could also try a dictionary:

<dtml-call "REQUEST.set('desc', {})"> . . . <td> <dtml-var expr="_[Category]"> <dtml-if "_[Category][0:2] <> 'No'"> <dtml-call "desc[_[Category]] = qty"> </dtml-if> </td>

And you can later loop over the keys() or items() methods of the dictionary.

To set things straight: dictionaries are not allowed as variables in dtml - they result in syntax errors. In fact Martijn himself :-\ suggested alternatives for dictionaries in http://www.zope.org/pipermail/zope/1999-August/009166.html Rik
