​@darcdesign.studio - logic has to be along these lines: 

using q1 as the m/choice question

on q1: 

• if q1 = A go to q-nextA  (q2 for this example)
• if q1 = B go to q-nextB  (q6 for this example)
• if q1 = C go to q-nextC (q10 for this example)
• if q1 = D go to q-nextD  (q14 for this example)
• if q1 = E go to q-nextE  (q18 for this example)

if you are using question groups for the other questions (or simple a linear set of questions) you need to put the following logic on the last question of each question group or linear sequence - ie q5, q9, q13 and q17 based on the above

on q5 (last question related to A being selected on q1)

• if q1 = B go to q-nextB  (q6 for this example)
• if q1 = C go to q-nextC (q10 for this example)
• if q1 = D go to q-nextD  (q14 for this example)
• if q1 = E go to q-nextE  (q18 for this example)
• otherwise go to ending or some other page

on q9: 

• if q1 = C go to q-nextC (q10 for this example)
• if q1 = D go to q-nextD  (q14 for this example)
• if q1 = E go to q-nextE  (q18 for this example)
• otherwise go to ending or some other page

on q13:

• if q1 = D go to q-nextD  (q14 for this example)
• if q1 = E go to q-nextE  (q18 for this example)
• otherwise go to ending or some other page

on q17:

• if q1 = E go to q-nextE  (q18 for this example)
• otherwise go to ending or some other page

and the very last question would have the logic to go elsewhere

hope that helps

Thank you for your help!
