we want to program a rating-experiment: StimPic - one question - two sliders - two sliderpics as labels. Its solved with a surveypage. Problem is  "/ required=true" in sliders. If no answer is selected (sliders not moved) and NEXT-click, only the sliders and the caption (/ questions) are visible. The StimPic and the slider-label-pics (/ stimulusframes) are invisible.What is my error in reasoning?/ 1= "b1.jpg"
/ 2= "b2.jpg"
/ 3= "b3.jpg"
