Regular expression does not evaluate answers properly.
when I add the regular expression like "Windows (and | or) Ventilators" with 90% score, and when the answer entered is "Windows or Ventilators", still it evaluates as incorrect and grades 0.
And also I have a question if we can check even numbers in this? like 3.2(4 | 6)??
I am not able to figure out why this issue is being caused. Hope someone can help with this.
Thanks in advance.
