Describe the bug
A clear and concise description of what what you were trying to accomplish and what went wrong. Vague statements like X does not work are not helpful. Imagine if one of your students sent you an email that said, "My program doesn't work, whats wrong with it?" Could you help them with only that to go on?

Preview of matching question renders nothing.

Javascript Errors
Many many errors can be quickly diagnosed from the Javascript Console error log. On Chrome this is View --> Developer --> Javascript Console, on Safari ⌥⌘i or Develop --> Show Web Inspector on Firefox Tools --> Web Developer --> Toggle Tools

Start at the assignment builder preview URL in the report and inspect the matching-question preview and the browser JavaScript console. Reproduce the blank rendering and confirm the preview displays the matching question without the reported errors.
