I added this and I get a never ending stream of : 
Use of uninitialized value $data[0] in join or string at 
/opt/catalyst/dbms/script/../lib/dbms/Controller/AccountView.pm line 59.

Which is just a debug statement, but it never ends. I comment it out and 
it acts like it is hung, my browser just says "Waiting for local Host".

I am actually quite close, I created a custom resultsource and have it 
populating the spreadsheet, but it keeps trying to iterate over the 86th 
row, which doesn't exist.
