I normally save and restore the record pointer during this type of operation.

SELECT Temp

lnRec = RECNO()

lcTyp  = alltrim(upper(thisform.grid2.column1.text1.value))
lcMac1 = alltrim(upper(thisform.grid2.column2.text1.value))
select * from temp;
  where alltrim(upper(temp.typ)) == lcTyp and alltrim(upper(temp.mac1)) == lcMac1;
  into array laResults

SELECT Temp

if _tally = 0
  append blank in temp
  replace temp.typ with alltrim(upper(thisformM.text3.value))
  go top
  thisform.grid1.refresh
else
  =mesagebox("found.....")
endif

GO lnRec  && This goes here or in the if statement
