Re: Boolean property node 'value' output is variant data type, not boolean.

Neither your main or subVI have a control reference. Did you attach
the correct files? An easy way to get the correct control reference in
a subVI is to create the reference to the control in the main VI and
drag the reference from the diagram of the main VI to the front panel
of the subVI. Another way is to drop a control refnum from the Refnum
palette onto the front panel, drop a control of the correct type onto
the front panel, and then drag the control onto the Refnum.
