It's because:
if (bonus=='Y')
is never true.

Try making bonus a char instead of an int.
tq stewbond. i really didn't realize the simple mistake =="
so sorry... and thank you :)
Often these things are just simple mistakes and you just need a second pair of eyes to take a look.
Which is one of the reasons programming never caught on in cyclopean communities.
