The logic used...
If QUESTION is filled, Calculate
(NOTE: For number field, use not equal to 0 in Total to Total)
Note: Typing here can be finniky, so I broke it line-by-line to make it easier...
TEXT:
(Just type a space here, click on the space to make it light grey or calculation will fail)

COMMASEP-FORMULA {QUESTIONTOTAL} COMMASEP-FORMULA
Summary: {QUESTIONTEXT}
