Hi, Axel <dtml-var "numbers[0]"> which is short for <dtml-var expr="numbers[0]"> You need to quote python expressions. -- Jim Washington Axel Missbach wrote:

<dtml-var numbers[0]> is equivilant to <dtml-var name="numbers[0]">. What you are writing is a (short) expression. Try: <dtml-var expr="numbers[0]"> You have stumbled upon the reason why the shorthand notation: <dtml-var x> and <dtml-var "x"> is discouraged in favor of <dtml-var name="x"> and <dtml-var expr="x"> respectively. They may be longer, but they are much more explicit. -- | Casey Duncan | Kaivo, Inc. | cduncan@kaivo.com `------------------>
