So I'm having the same problem. Trying to answer the following "random" question:
How many rims does a crawler or Scaler have?
I've entered four, Four, 4, five, Five, 0, zero, Zero...........must be trick question.......cause I'm not gettin' it?
I tried the link above, but it doesn't work any longer, which I can understand as this post is almost 5 years old.
