I am new using calculated questions and wildcards. I am trying to set up an exam for my students on a finance course. To do that, I need each wilcard value to depend on the value of the other wildcards. For instance, I have Revenues as one wildcard and I will select a range for it. But then I need Costs (another wilcard) to be a certain percentage of whatever value Revenues have. However, when I try to do that, I get this message: "Wild card value is not a valid number". Is this possible?
I've seen some old messages with the same problem but I didn't really get the solution so sorry if this has been answered before. I do not have the "Formula" type of question I've seen mentioned.
Thanks a lot.
