RE: [Zope] Newbie DTML: How do you just declair a veriable.
When I do that it sets the variable to a string that says welcome rather that the dtml method named welcome. If I use <dtml-call "REQUEST.set('myvariable','dtml-var welcome')"> it does nothing.

I am developing a small application and in part of it I want one page to recursively call itself and display a new sub-page depending on which link was clicked on. I am trying to just create a variable that I can set to the new method but I always get an error.
How do you just make an arbitrary variable.
I tried <dtml-var somename> = <dtml-var somemethod> and it did not like that complained about there not being a somename well that's what I am trying to make.
The easiest way is to use REQUEST.set: <dtml-call "REQUEST.set('myvariable','myvalue')">
Another way to do it is to use dtml-let. This is "cleaner" if you will only need the variable for a short time. <dtml-let nums="(4,5,6)"> nums forward: <dtml-in nums><dtml-var sequence-item> </dtml-in> nums backward: <dtml-in nums reverse><dtml-var sequence-item> </dtml-in> </dtml-let>
Nums only exists between the two <dtml-let statements>. -- Stephen Pitts smpitts@midsouth.rr.com
not sure if i get you right. if you want to * include a string 'welcome' use <dtml-call "REQUEST.set('myvariable', 'welcome')"> or <dtml-let myvariable="'welcome'"> * include the value of a variable named 'welcome' use <dtml-call "REQUEST.set('myvariable', welcome)"> or <dtml-let myvariable="welcome"> pretty much everything inside " quotes " is pythonic in DTML. you might want to take a look at the DTML ref (http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.html), esp. the section "The expr attribute" hth peter.
