May be the problem in the order of evaluation in the replace command?

When I do the following:

BROWSE NORMAL FOR EMPTY(dc_crdno)
IF NOT thisform.NoCCMask
	replace dc_crdno WITH REPLICATE("*",12) + RIGHT(ALLTRIM(dc_crdno),4) ;
	FOR NOT EMPTY(trim(dc_crdno, CHR(0), chr(9), chr(10), chr(13), chr(32), chr(160)))
endif

I see the empty rows just fine. However, I still end up with the 12 * for empty rows. What should be the correct code?

I'll try replace all and IIF instead.

Thanks.

UPDATE. This didn't work either

replace dc_crdno WITH IIF(EMPTY(dc_crdno), '', REPLICATE("*",12) + RIGHT(ALLTRIM(dc_crdno),4)) all

I give up.
