TERS file invalid

SOLVED

I have asked previously about the process to go about claiming annual leave paid to staff back from TERS but received no responses.  We paid all our staff full for April using a combination of their various leave.  I generated the csv file on Pastel Payroll following the instructions, added their shutdown income (which was their nett wages paid to them) and submitted.  I did this twice but it still tells me the file is invalid and to resubmit.  Now what?
