Data type returned 
Originated in 
FileMaker Pro 7.0
Values are text items separated by carriage returns. You can place several items together to create a carriage-return-delimited list of values. A value can be empty, a single character, a word, a sentence, or a paragraph. When you press Return you start creating a new value. The last value will be recognized with or without a carriage return.
When the text parameter is a literal string as in the example below, you must insert a literal carriage return character between each item in the list. In the Specify Calculation dialog box, click the button to insert a literal carriage return character.
ValueCount(“Item 1¶Item 2¶Item 3”) returns 3.
ValueCount(ValueListItems(“Employees”;“Employee Names”)) returns the total number of values in the Employee Names value list in the Employees database file.
