Hello, 

I have a question considering a script that I'm writing with Inquisit 3. 
There are three different tasks and the participants can choose in which order they make these tasks. 
This is now possible with a surveypage.
However, when one task is completed this task should not be an option anymore in the dropdown menu. 
Is there a simple way to realize such a proceeding?
See part of the script below. 

Thanks in advance!
Johanne
