App Store on Iphone doesnt show my app updates? Help!

My iphone 4 all of the sudden said i have an update so i went to update an app and it says its refreshing then stops and no update shows up. The app store just says "updates" on the top and its white where the update should be. Anyone else have this problem? Any fix? Links to fix? Help!

It was probably an error and there wasn't an update.
