Complete Text: "Error: You left necessary fields blank or entered invalid values. Review and correct any fields with "!" next to them."
You must have tried to continue to the next step or save your changes on a page with fields left blank or filled with invalid data. This error can appear on many pages. Look on the page for "!" to identify which fields need attention. Invalid data could mean data that is outside of the range of acceptable values, alphabetic letters where numbers should go, or other characters inadvertently typed in. If a blank field is marked, you must put something in it for the page to be valid.
