[Zope] Parameter from DTML-Document to SQL-Method

[Axel Missbach]

Hi to all,

I am trying a long time to get the result of an query in the document,
or perhaps get the parameter in the query.
It looks like this: 

<dtml-let value="'Test'">
	<dtml-in expr="sql_query(para='<dtml-var value>')">

	<dtml-var code>   #code is part of the query-result
	.
	.
</dtml-let>

Viewing the document, i got no result (and no error).  
Testing the query with value= Test, the result is ok!

thanks very much in advance
