I ask them what 2*3 = and when they do not type in the correct answer I give them an error.
NO...….What does 2*3 =
Two things how can I pick up the answer from the question and use it in the error message
1. like NO.....2*3 does not = [answer]
2. When I put a number in the question element no error comes up until I click to another element.
