filtered overview question - by: djarnold

Hello!
I am using expresion manager placeholders for doing a filtered overview based on answered questions.

example
group 1
if( ! is_empty(q1), join("- ", q1.question, ": ", q1.shown),
group 2
if(q2_SQ001 == "Y", join("- ", q2_SQ001.question, ": ", q2_SQ001), "")
if(q2_SQ002 == "Y", join("- ", q2_SQ002.question, ": ", q2_SQ002), "")
if(q2_SQ003 == "Y", join("- ", q2_SQ003.question, ": ", q2_SQ003), "")
if(q2_SQ004 == "Y", join("- ", q2_SQ004.question, ": ", q2_SQ004), "")
group 3
............


i need to show every group title using placeholders only if question of this group are answered.... is there any way to do this?
the multiple choice with comments do not show the question title only the subquestion so i need to show the question title only if the question is answered is there any way to do this?

Thaks for the help
