Calling Teststand from LabView

[Clint Eastwood]

I've written a front panel GUI in LV 7.0.  The operator presses a
particular "button" to execute a certain test.  How do you call a
Teststand 3.0 seq ( that I've written) unique to that button when the
operator presses it ?  The LV Operator Interface shipped with LV was
of no help.
