Address Check Window
From FloristWiki
The Address Check window appears if FTD Mercury does not understand the address that you entered in an address field. This does not necessarily mean that the address is wrong; check the information in the window and click Save.
Following is an example of how the address information should appear in this window:
Street: 123 Main Street Apt 4
City: Long Grove
State/Province: IL
ZIP/Postal Code: 60047
