How to set that a chosen website is opened to a respondent after completing survey?

At the end of questionnaire we have an option that allows a chosen website to be opened to a respondent after completing a survey (such as a website of a company or of an organisation).

We enable that function by opening tab 'Edit' – 'Questionnaire' and clicking on “Thank you page” (final question of a survey). Editor is opened where we choose “Jump to link” on the right side of “Close survey instead of link” option. URL is then inserted into URL of a website, we wish the respondent to redirect to after the survey is completed.

Example of a survey where after its completion respondent is redirected to the website of Center for Social Informatics.
