Documentation difference - Dynamic Dropdowns.
The Create Dynamic Array help file says the following:
To create a dynamic array containing your Child List options
In the server behaviors panel group, click the plus (+) button and select WebAssist > Dynamic Dropdowns > Create Dynamic Array. The Create Dynamic Array dialog box will open.
In the Recordset: list, select the recordset that retrieves the records for your Child List from the database.
In the Parent ID field: select list, specify the recordset column that correlates to the unique id from your Parent List records.
In the Child ID field: selection list, specify the recordset column which provides the unique id for the records containing your Child List information.
In the Child Text field: selection list, specify the recordset column containing the text values you wish displayed for the options populating your Child List.
Click OK to apply the server behavior.
The wizard actually says "Child Value" for the part that says "Child Text" in the help file. Child Text makes more sense.. as it is not being used as a "Value" ;)
