Sorry, but I dont see any line of used DTML method to produce this error. In 
fact, the error is at line 313 (this number is not present at traceback) of 
DTML method named "titulni":

NameError: name 'kalendar_titulni_pouze_akce_str' is not definedLine 313 
where is the error looks:<dtml-call "REQUEST.set('akce', 
kalendar_titulni_pouze_akce_str)">Is somewhere some extra product or patch 
to show partial code where is error?Thanks, JL.
