I have several response questions that should conduct directly to the end message. I cannot understand how to set this condition.

You can set condition on a question or a group of questions so it is shown only when the condition is met. If the condition is not met the question or group will be skipped.

As Elisa says. Conditions are there to hide certain questions - in your case this would be all questions until the end. This can be quite a bit of work as Limesurvey doesn't allow "jumping". You can't say "if this is answered, go directly to end". You need to configure in each question that it should be hidden. This is quite flexible, but can mean a lot of work in your case.

However, it would be good to get a little bit more of background information. Because you actually might want to "screen" people out. So people that don't fit your criteria should be screened out and not continue. In this case you can use quotas (zero quotas) and define an alternative ending page for those screened out in this condition.
