Excel 2007 : Stop pivot table from displaying blank rows

Many to all that help those of us that are learning.

I have a table that combines data from three different reports. I have a pivot table sourcing this table for its data. The problem is the data table is built to handle 500 lines. The number of lines of data is dependent on the size of the customers fleet.

Please see the attached example. (the # REF errors are not in the real report) The lines highlighted in yellow (line 5-502) are returned as blanks in the pivot table. How can I keep my data table capable of 500 lines and not return blanks to the pivot table.

Thanks in advance for all the help you provide.
