Hi, Please, whats wrong with this code? <dtml-let est="_['\'./'+estagio+'/aula\'']"> <dtml-call "RESPONSE.redirect(est)"> </dtml-let> estagio is a valid variable (containing the value Aul00) and Aul00 is a Folder but I get the following error: Error type - KeyError Error value - './Aul00/aula' How would be the correct way to perform that redirection? Thank you very much.
