[Zope] Altering values from HTML forms before SQL insert

[Neil Bartlett]

I have a HTML form that returns a value that I need to alter before I pass
it to a SQLMethod.

To do this I created I've assumed I should use either dtml-with or dtml-let
to create a new variable with my desired value and then call the SQL MEthod
within the dtml-with.

Some sample code is as follows.

SQLMethod:

ID:odbcInsertTalk
arguments: LocationAndTime
Query:
insert into talk (LocationAndTime) values (
<dtml-sqlvar LocationAndTime type=string>
)


DTML Document:

<dtml-var standard_html_header>
	<dtml-with "_.namespace(LocationAndTime=Location+'--now')">
		<dtml-comment>
			<dtml-call odbcInsertTalk>
		</dtml-comment>
		<ul>
			<li>Location: [<dtml-var LocationAndTime>]
		</ul>
	</dtml-with>
<dtml-var standard_html_footer>

I get my desired values for LocationAndTime for the code as shown however,
if I uncomment
<dtml-call odbcInsertTalk>
then I get a complaint

Error Type: Bad Request
Error Value: ['LocationAndTime']

odbcInsertTalk works fine when I test directly from the SQLMethod manager
page. I t also works if I remove the <dtml-with> and change the HTML form to
send the exact name (of course this does not have the value I want but it
does get correctly added to the DB)

 I'm using ODBC DA version ZODBCDA-3.1.0b2-win32-x86.tgz.

Zope version: Zope 2.1.4 (binary release, python 1.5.2, win32-x86)
Python version: 1.5.2 (#0, Jul 30 1999, 09:52:18) [MSC 32 bit (Intel)]
System Platform: win32
Process ID: 217 (264)
Running for: 3 hours 24 min 35 sec

Any help would be very apprecitated.
