Tap not working

Hi I have created a windows phone app 7.1 that counts the taps, it has a reset button as well, I have coded it and no errors are showing, the app opens perfectly in the emulator but when you tap the screen no count happens, I have been through the code so many time Im nearly dizzy http://www.barakasoft.com/script/For...iley_smile.gif .

anyone who can spot anything wrong would very much appreciated.
