Only the first record was changed back to .F. in the now CHOOSE field (not SELECT). The other records I had previously made .T. (or selected) did not cahnge; they remained as .T.

Here's the code in the UN-CHECK ALL button:

WITH ThisForm
	REPLACE ALL SPECS.Choose WITH .F.
	GO TOP
	.SaveCancelStatus()
	.Refresh()
ENDWITH
