Error after Repeat group

Please I am a beginner with the application.

I get this error Cannot get question prompts from a non-field-list group, with a question that follows but not part of the repeat group.

How can I build this?

group: the number of an activity report (integer)
repeat group contains:
question list: List activity; Hours, etc.

The next question does not belong to the group list and when I test on the application it gives that error message.
What is the best way to resolve this?

Question 2.
What is the statement that will help mobile users to select the current time of the tablet/phone? E.g. Interview start time
