Why do my data show up on the AMP251 but not the AMP256 report?

if you run the AMP251 report it will show all the data and tell you if it's valid or not.  If the data submitted shows a difference between the actual flow rate and the indicated flow rate of more than 10%, the data will be invalid and should not show up on the AMP256 report.  The AMP251 will show you what the percent difference is and indicate where the data is valid or not.  The AMP256 report will summarize only valid data.
