Well, obviously if you pass a formvariable named formvar1 into the page with a value of oldValue, then use this tag at the top of the page:[text]formvar1=newValue[/text]... the new default variable hierarchy will make webcat interpret all occurrences of the [formvar1] tag as newValue, NOT oldValue. But that's because it's finding the text variable value of formvar1 not the formvariable value of formvar1. Clearly this is because the new hierarchy puts text variables on top of formvariables in the hierarchy.To get the true formvariable value, you have to use this code:[formvariables name=formvar1&exact=t][value][/formvariables]... and the result will still be oldValue, because this code looks *only* at the existing formvariable values which have not changed, even though it may LOOK LIKE they have changed if all you use in your templates are tags like [formvar1] ...Confused enough? ================================ Kenneth Grome, WebDNA Consultant 808-737-6499 http://webdna.net ================================------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
