I'm traying to convert variables that I recieve from a JavaScript tu ISO date format using:

<dtml-var Arrival fmt=ISO> <dtml-var Departure fmt=ISO>

This Dates will be then used to send an SQL request to a database so I use:

<dtml-in expr="Disponibilidad_cal (fechain=Arrival, fechaout=Departure)">

And allways shows same error:

Zope has encountered an error while publishing this resource.

I have no idea of what am I doing wrong, can anybody help me?

Generically, that error message means that you're passing the database more variables than it expects. So... are you sure that your query is expecting both of those? -- Nick Arnett Phone/fax: (408) 904-7198 narnett@senti-metrics.com

Almost surely, "Arrival" and "Departure" are strings and not "DateTime" objects. Unlike "DateTime" objects, strings do not have an "ISO" method. Therefore, "ISO" is interpreted as a (C) format string. As it does not contain format specifiers ("%spec"), it is unable to convert the argument. You find details about the "fmt" attribute in <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html> Your problem will go away when "Arrival" (and friends) are "DateTime" objects. Depending on their format, you may be able to use: <dtml-var expr="ZopeTime(Arrival)" fmt=ISO> Dieter
