I am having problems with my program. WHen I run it, it asks the user for the album, the title, but then it just exits the loop without asking for the price and the sale tax. Any ideas what's going on?
This is a sample run
Discounts effective for September 15, 2010
Classical 8%
Country 4%
International 17%
Jazz 0%
Rock 16%
Show 12%
Are there more transactions? Y/N
y
Enter Artist of CD:
Sevendust
Enter Title of CD:
Self titled
Enter Genre of CD:
Rock
enter price
Are there more transactions? Y/N
Thank you for shopping with us!
