Export query to .csv - losing headers

[Kathy]

I'm using the following to export query results to a .csv
file:
DoCmd.TransferText
acExportDelim, "EqtExportSpec", "qryExportCSV", "C:\MyFile.
csv", True

It works fine for me, but when I send it to the user,
their .csv file gets created without the header. What
have I done wrong?

Thanks,
Kathy
