Cpk ??? wrong ???

Hi, can someone tell me why I getting a strange Cpk value? I know that that if you get a negative ( - ) cpk is because your mean is above or under spec's limit, but what I getting is -1.00000. Do I nee to adjust the setting on Datapage...help......

    I recently switched over to DataPage+ v4.1 and we are having an issue with tolerance. The program was written with the tolerances both positive, as it should be but they are coming into DataPage that way too. I could have sworn that there was a check box or something that made the negative tolerance negative but I can't find it. Can anyone help me?
