Dynamic Survey Completion URLs
Do not use the Dynamic URL in the Survey Complete section of the survey properties. This is not compatible with Pavlovia Surveys
Instead you should use the Experiment Flow section of the overview page.
Here I have set the Completion URL to
"https://" + {block_1/question4} + {block_1/dissent}
dissent is an expression based on the consent question
iif({question1} = false,"google.com","")
question4 is an expression based on a later question
iif({question2} = 1,"moryscarter.com/vespr",iif({question2} = 2,"pavlovia.org",""))
Note that in both cases I have set the value to be an empty string “” if the condition is not met.
Try it
N.B. The survey completion URL must be blank if your survey is embedded.
