Thanks! Zope lets me know when I do this, and I pay by waiting a long time for things to save and then having to cut and paste things somewhere to figure out the line number... wish there was a cool editor for dtml that worked on linux... So anyway, I pay in currency of time whenever I improperly nest something, and the hard punishment teaches me fast :) Ale On Mon, 8 Jul 2002 10:01:04 -0700 "Charlie Reiman" <creiman@kefta.com> wrote:

For your own sanity, try not to use dtml vars with "-" in them. This expression:

<dtml-let other-this="other-this + 1">

Will get parsed as _['other-this'] = other - this + 1

since python does not support variable names with a "-"

Also, dtml-let sets up a nested scope. You are trying to cross your if expression with your let expression:

<dtml-if><dtml-let></dtml-if></dtml-let>

won't result in a happy compiler. This is like tring to write a math expression like

(5+[4-3)+7]

If you want to set variable values, look into the SetTag product and leave dtml-let and dtml-var alone. They generally don't do what you want.

Hi,

I'm trying to output reports based on the result of a database query contained in a session variable.

It goes

<dtml-in loopname mapping> <dtml-var this><dtml-var that><dtml-var the_other><br> <dtml-if "sequence-item > size"> If at the end of the current sequence size, summarise all further results:

<dtml-let other-this="other-this + 1" other-that="other-that + 1" other-theother="other-the_other +1"

...

<dtml-if sequence-end> <dtml-var other-this> <dtml-var other-that> <dtml-var other-theother> </dtml-if> </dtml-if> </dtml-let> <dtml-in>

The problem is that the variable is a session variable: this is I think why anything like "<dtml-var sequence-step-size>" gives a key error. Is there a way to de-map things when working with the sequence?

Thanks,

Ale
