Fragment Syntax Problem

My name is Rob Sobol.

I have been working through a book called Head First Android Development.

I hit a syntax error in a simple exercise that uses one fragment. I have been trying to figure out the error for days.  I am hoping some in the forum can download the attached project and show we where I went wrong.

'Inconvertible types; cannot cast 'android.app.Fragment' to 'com.hilights.rsobol.workout.WorkoutDetailFragement'

It most likely is an obvious error that a newbie like me cannot see.

Thank you in advance for your support,

Rob
