Other people answered your conversion question, I just wanted to point out that the ':int' notation is meant for use in qualifying HTTP POSTED data, like that coming from a form. For example: <form> <input name="bob:int"> </form> This will cause ZPublisher to try and turn the value of this element into an integer. This is the only place the ':int' notation makes any sense. In your example, you have confused this notation with that of the let tag. -Michel "Brian K. Holdsworth" wrote:
I am trying to do the following:
<dtml-let x:int="REQUEST.get('prod_config')" item="_[REQUEST.get('prod_id')]" price="item.price_list[x]"> <INPUT type="hidden" name="chargetotal" value="<dtml-var price>"> </dtml-let>
The prod_config variable is a number (returned as a string) from a SELECT list. The prod_id variable is the id of an object in the same folder as this method that has a price_list attribute. price_list is a list of strings representing prices.
This results in a "Name Error" where Zope cannot find "x". If I change line 3 to this:
price="item.price_list['x']">
it fixes the Name Error, but then I get a "Sequence Index must be an integer" error on price_list['x']. I would have thought the use of "x:int" in my <dtml-let> would take care of this issue. Seems I can't win!
Does anyone know the correct way to do this lookup?
