LabVIEW DLL Error "You Cannot Select a Polymorphic VI Because of Ambiguity in Selecting a Connector Pane"

Primary Software: LabVIEW Development Systems>>Full Development System
Primary Software Version: N/A
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:

I receive the DLL error when trying to build a LabVIEW DLL in LabVIEW 6.x.

You cannot select a Polymorphic VI because of ambiguity in selecting a connector pane. Please select a subVI of the Polymorphic VI instead

What can I do to correct this error?

Solution:
You cannot use a polymorphic VI to create DLLs because a polymorphic VI actually consists of multiple SubVIs each with the same connector pane pattern but different data types for inputs and outputs. Therefore, the data types of the DLL parameters can not be established.

Use an instance of the polymorphic VI to create the DLL. Follow the links below for further information on polymorphic VIs.
