Hi gregfromrehoboth beach,
Welcome to the Support Communities!
Here are a few things to try:
Sign out of the iTunes Store account in Settings > iTunes & App Store
Quit the iTunes app:
iOS: Force an app to close

Then restart and/or reset the iPhone:
iOS: Turning off and on (restarting) and resetting
http://support.apple.com/kb/HT1430
If you have tried those two things, refer to page 146 in the iPhone User Guide to Reset All Settings:
iPhone User Guide for iOS 7
manuals.info.apple.com/MANUALS/1000/MA1565/en_US/iphone_user_guide.pdf
Hopefully that will get you back on track ...
Cheers,
