Button updates random variables though the code doesn't say so
I have created the attached exercise generator which also evaluates the answers.
Here the students are going to move a parabola so it fits to specific criteria regarding the constants; a, b, c and d.
The problem is that when I press the evaluation button "Evaluer graf" (meaning "Evaluate graph"), the criteria is being updated. And I can't find a way to solve this problem.
I hope someone can help me.
