Hi, I have several DTML Doc named "caso" each of them in a diferent directory. Two of these "caso" documents have a property called "idioma" with type string and value "en". The others do not have this property. In the parent directory I have another document in which I want to check this property *when* available. So I do: <dtml-if caso.idioma> <dtml-if "caso.idioma == 'en'"> <h2>What is your diagnosis?</h2> <dtml-else> <h2>¿Cual es su diagnóstico?</h2> </dtml-if> <dtml-else> <h2>¿Cual es su diagnóstico?</h2> <**** </dtml-if> I want to test if this property exists. If it exists and its value is "en" then print a text in English. Otherwise print it in Spanish. The above DTML code always returns the text marked with "<****". I've tried puttin the first if in double quotes like <dtml-if "caso.idioma"> but it fails when the document does not have this property. Thanx for any help. Regards, Rafa -- Linux.
