How do you differentiate between the seq-items of nested dtml-ins? I tried the following code: <dtml-in "instances.objectValues(['Coupon ZClass'])"> <dtml-in SearchCategory> <dtml-if "_['sequence-item']=='Auto' "> <dtml-call "resultsList.append(_['sequence-item'])"> </dtml-if> </dtml-in end SearchCategory> </dtml-in end instances> Where: instances is a folder containing the coupon instances Coupon ZClass is the meta type of the zclass SearchCategory is a list from a form resultsList is a list containing instances of Coupon ZClass matching the search criteria Auto is a property of Coupon ZClass When I try to run a search an error page pops up saying "strings aren't allowed as input in the in tag." The property Category of the zclass is the type lines. "Auto' is one of the values in Category. In <dtml-if "_['sequence-item']=='Auto' "> I am comparing the current element of SearchCategory to one of the values in Category. In <dtml-call resultsList...> I want to append the instance and not SearchCategory list. Peacefully, Aaron
