Hi Jose
I don't seem to get the same error as you.

I've attached my working example - perhaps you could see where you went wrong by comparing my version with yours.
Just as a side-note, you can also use the 'end' question type to capture the end date and time of the survey.
end | End date and time of the survey. This is a hidden field, not visible on the form. |
