Occasionally, we get a Bad Tab Column 9 or Bad Tab Column 36 when running reports after submitting ECS claims. Can someone explain what this error is? I have asked but still do not understand why it occurs or what to do about it or prevent it. Yesterday, we got a Bad Tab Column 9 and it froze one workstation out but then it let us in. At times, the Bad Tab Column 36 will freeze out all workstations and those reports are unavailable. Unfortunately, for the error yesterday, it did not submit all the claims, we submitted those that did not go through and today we got duplicate claims. Oh well....but can someone explain this?? Thanks!!
