Question: Error using the Tutorial on limits

When I solve in worksheet mode the limit of (2*abs(x-2)+abs(x+1)-3)/(abs(x^2-4)+x-2) evaluating the limit in x=2- the result is 1/3 and in x=2+ the result is 3/5, but if I try to use the Tutorial/Single Variable/Limits, an error occurs.

Any Suggestion?
