Hello All,
I am new to SQL and I am having trouble figuring out why I am getting duplicate entries in my report. For some reason it is only occurring on two county/district combinations. Please take a look at this screenshot to see my data. Please let me know what you think. The duplicates occur in Conner Service Center and Sterling Heights. I have went through line by line debugging the tables and I think the error is occurring somewhere in my number of reads or number of errors block.
--Checks whether any of the error checkboxes are checked.
--If 5 boxes are checked thats 1 error
