The file is working.
The problem is that in this special case the two lines are overlapping, so there isn't a unique solution for the point A of intersection, and the point is therefore not defined.
You should modify your displayed text and show it only when A is defined.
See IsDefined command - add IsDefined(A) as condition to show your text containing the coordinates of the intersection.
