Merhaba, qualtrics üzerinden bir çalışma yürütüyorum. Çalışmada öncelikle katılımcılara bazı alış seçenekleri verilmekte ve daha sonra alınan ürünlerin satışı istenilmektedir. Gömülü verideb veriler çekiliyor ama satış fiyatı sonuç olarak gözükmüyor. Acaba bu konuda yardımcı olabilecek birisi var mı?
Şimdiden teşekkür ederim.
