[Zope] External method building a ksh script

5 May 1999

      I am puzzled on this. The following dtml calls the following external
method makeScript (template2 is a property on the containing folder
which is the text of the ksh script template):

<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>

<!--#in expr="REQUEST.form.items()"-->

<!--#var sequence-key-->: <!--#var sequence-item-->
<br>
<!--#/in-->

<!--#var expr="makeScript(template2,REQUEST.form)"-->

<!--#var standard_html_footer-->

I get the following error:

Any ideas? (I know about the extra colons in the var names, have to deal
with that as well.)
