Dennis,
When you're satisfied with data and should be saved call :
tableupdate(2,.t.,"tablename")

This is a quick start and work in many cases.
Of course parameters might change depending on your case. Look at its help for parameter definitions. It returns a logical meaning if update was succesfull or not. You should check why it failed (ie: it might fail for someone else edited in between - curval() and oldval() do not match).
Help about buffering detailly explain and sample it. Also check wizard buttons save/edit code (wizstyle.vcx - txtbtns).
A save routine (a quite rough skeleton) :

begin transaction
if lEverythingIsOK
  if tableupdate(....)
     ....
     end transaction
  else
     ...
  endif
else
  rollback
endif

Also there is tablerevert().
