Here is my code now:

That's because there is no possible case where the third dtml-call will ever be invoked. If BuscaCertificado is empty (no records found), there's nothing for dtml-in to loop over. Control passes to the next line after </dtml-in>. Since there is nothing after that tag, your return is a blank screen... or more accurately, a screen full of non-rendering whitespace.
Try something like this instead:
<dtml-if txtCertificado> <dtml-if BuscaCertificado> <dtml-call "RESPONSE.redirect('http://url_1')"> <dtml-else> <dtml-call "RESPONSE.redirect('http://url_2')"> </dtml-if> <dtml-else> <dtml-call "RESPONSE.redirect('http://error_url')"> </dtml-if>
HTH,
Dylan
