Description:

PURPOSE: to show the first available value from a list of fields.

SPECIAL CONSIDERATIONS: it is assumed you are pointing to fields (or parameters) and the list of fields are separated by semicolons and the whole string is encapsulated in quotes


ShowValueCascade ( "firstChoice; { secondChoice; thirdChoice; fourthChoice...}"; altText)

given the field values:
Student::FirstName = (empty)
Student::MiddleName = "Joe"
Student::NickName = "Sticky"

ShowValueCascade ( "Student::FirstName; Student::MiddleName; Student::NickName"; "The Student With No Name" ) will return "Joe" since it's first on the list

given the field values:
Student::FirstName = (empty)
Student::MiddleName = (empty)
Student::NickName = (empty)

ShowValueCascade ( "Student::FirstName; Student::MiddleName; Student::NickName"; "The Student With No Name" ) will return "The Student With No Name" all the referenced fields are empty
