Sorry for jumping in, but this is pretty common, well at least it was with me when I first started using VFP! You need to use the REPLACE command. As in:
REPLACE unlock_value WITH ThisForm.oCallingForm.nUnlockVal IN (v_view)

Just setting the view.fieldvalue = anothervalue doesn't work, (although intuitively you would think it would) as you found out!

Hope that helps!
