I have declared a variable local in a form class method, yet it seems not to be local. Here is the code:

THISFORM.grdfind.RECORDSOURCE = THIS.ccursorname
LOCAL nColumnCount, nColNumber
nColumnCount = THIS.grdfind.COLUMNCOUNT

FOR nColNumber = 1 TO nColumnCount
	THIS.grdfind.COLUMNS(nColNumber).CONTROLSOURCE = ;
		THIS.ccursorname + "." + THIS.afieldnames(nColNumber)
ENDFOR

If I run through this method twice it blows up because nColNumber = 5 (nColumnCount = 4). If I suspend the code below the ENDFOR, nColNumber = 5 at the end of the first pass. Is this normal? I thought that nColNumber would never be greater than 4? On the second call to the method, nColNumber starts out at 5. I use this same variable in the calling program (declared local) and another method in the same form class (also local).

TIA
