Any valid VB.NET/ADO.NET expression including a field (or fields) from the address table

Specifies the expression for additional information displayed on the GuestLookup.aspx page if there are multiple matches from a lookup (to help a visitor/guest identify his record in the database). Generates an additional column of information in the guest lookup grid for multiple matches. For example, SUBSTRING(phone, 7, 2) would give the last two digits of the phone number or just a field name like zip would return the zip code.

InfoExpr = zip+' - '+SUBSTRING(phone, 5, 4)
