Thank you for your help, but... I have simplified my code, replaced dtml-return for dtml-call... and it still doesn´t work. Here is my code now: <dtml-unless txtCertificado> <dtml-call "RESPONSE.redirect(URL1+'/InicioIC'+'?msg_error=Error: debe introducir un número de certificado')"> </dtml-unless> <dtml-in BuscaCertificado> <dtml-if sequence-start> <dtml-call "RESPONSE.redirect(URL1+'/InicioIC'+'?msg_error=Error: el certificado '+txtCertificado+' ya existe')"> </dtml-if sequence-start> <dtml-call "RESPONSE.redirect(URL1+'/IC'+'?txtCertificado='+txtCertificado)"> </dtml-in> So I first check if the user has entered a value for txtCertificado, and return with an error message if it is not the case. The program does it right. Then I check for txtCertificado in the database (with th ZSQL method BuscaCertificado) and if it is found, it returns with an error message. The program also does it right. But when it finds the third case (there is a value for txtCertificado, and it is not already in the database) it does nothing. Instead of going to URL1+'/IC', it just shows a blank page. I really can't understand what could be the problem, because the logic seems so simple. Just in case that it matters, I am using Zope 2.6.1 on Windows. Borja Prieto Alanta

Hehe. You can also use Zope and easyly forget that DTML exists ;) At least for templates and logic.
Guess I walked into that one... :-)
