The code now:

		public nMyBugs
		public arMyErr
		dimension arMyErr[1]
		nMyBugz = AError(arMyErr)
		lCSPResult = CursorSetProp('buffering',1,'Customers')
		select CustUpdate
		wait window 'ok point 1'
		select CustUpdate
		lnFieldCount = AFIELDS(laFields,'CustUpdate')
		FOR nNothing = 1 TO lnFieldCount
			wait window 'ok point 2'
			DO CASE
				CASE GETFLDSTATE(nNothing,'CustUpdate') = 3
					wait window 'ok point 3'
					SETFLDSTATE(nNothing,1,'CustUpdate') 
					wait window 'ok point 4'
				CASE GETFLDSTATE(nNothing,'CustUpdate') = 4
					wait window 'ok point 5'
					SETFLDSTATE(nNothing,2,'CustUpdate') 
			endcase
		ENDFOR
		tableupdate(1,.t.,alias())
	else
	endif

In the debugger, this is what I have in the Watch Window:


Name / Value / Type

getfldstate(nNothing,'custupdate') / 4 (in red) / N
nNothing / 1 / N
lCSPResult / .t. (in red) / L


Then I click my commit button and get the error 'invalid argument etc' and the Trace window arrow is pointing to setfldstate(nNothing,2,'custupdate').

The Locals window for my cmdbutton shows:
arMyArr:
[1,1] = 11
[1,2] = "Function argument value, type or count is invalid"
[1,3] to [1,7] is .NULL.

nMyBugs = .f.
nnothing = 1
nresult = 6
lnfieldcount = 21



At this point, my code never makes it to TableUpdate(), a few generations ago it was returning .f. and I could not see any changes in the base table.

>You are not checking the return values from the cursorsetprop() or the Tableupdate() and either of them could be returning .F. indicating that they did not do what you asked. You still haven't told us if TableUpdate is returning .T. indicating that it did, in fact, do the update.
