Hi, inside an expr you cannot use DTML anymore. Everything inside "" is a kind of Python parallel universe ;) So, you'd just use something like (untested): <dtml-in ...> <dtml-var expr="myFunction(myField1)"> .... ru, peter. On Mon, 23 Apr 2001, Uwe Fechner wrote:

Hello everyone,

I'm a newbee with zope and have the following problem:

I want to display calculated results from an SQL-Database.

I created an object 'Script (Python)' that looks like:

## Script (Python) "myFunction"

## bind container=container ## bind context=context ## bind namespace=_ ## bind script=script ## bind subpath=traverse_subpath ## parameters=myParam ## title=myFunction ##

return myParam[0:-1]

Then I created a dtml document object with the content:

<dtml-var expr="myFunction('test')">

If I choose 'View' I see:

tes

This is what I have expected (the function chops the last character).

Then i tried:

<dtml-in select_all_from_myTable> <p><dtml-var myField1></p> </dtml-in>

If i choose 'View' i see:

test1 test2 test3

Then I tried:

<dtml-in select_all_from_myTable> <p><dtml-var expr="myFunction(<dtml-var myField1>)"></p> </dtml-in>

If I choose 'View' I get:

Expression (Python) Syntax error: invalid syntax

So, how do i have to write this call, that it chops the last character of myField1 ?

Best regards:

Uwe Fechner
