automatically remove error rows when refresh

I Have create a report using 3 excels files from Sharepoint, These files contain a number of spreadsheets related to each employee. All files are mergered into the one database by the Append Queries i have also created a  remove error step in the applied steps, however everytime i refresh my data i get 22 error lines which i have to manually remove errors. These lines are the header lines for each employee spreadsheet. Is there anyway of getting the system to refresh but ignore these lines?
