How do i make sure that respondents answer questions basing on what they chose in a previous question. For example, i asked a multi-select question on the sources of startup capital.

In the next question, i want them to answer what percentage they got from each source selected in the previous question.

You can use a roster to implement, where, thus select your appropriate responses, then answer the followup questions based on that selection.
