Error on Range("A1").SpecialCells(xlLastCell)) - ms-access

Question

I am getting a "Method 'Range' of object '_Global' failed" error about 50% of the time I try to run the below code. Debug takes me to this line:
Set rng = xlWS.Range(Range("A1"), xlWS.Range("A1").SpecialCells(xlLastCell))
Can anyone help with this problem?? Thanks.
