I know this topics has been covered many times. But after having visited many pages and tried many things I am still unsuccessfull. I try to randomly assigned 3 questions (each made of a MCQ with pictures). I am a pure neophyte, but I think I have understood the concept behind and I have created my equation question which looks to work but then none of my questions appear and the "==" appears red in the relevant equation (see attached). I have tried to insert the conditions through the "set the conditions" buttons and through the relevance field, but no success.
Could someone maybe help me? I have also joined the file of the my questions group.
