problem uploading Numbers file to Discogs.com

I wanted to upload my inventory, saved in csv format, to Discogs.com after I’ve made some changes to it.

It didn’t work and I got these error messages:

“Skipped row 2 because ERROR: listing_id is a required field and not in this row.”

“ Skipped row 14 because ERROR: header has 1 fields and this row has 2 fields”

I communicated with the Help at Discogs, they checked out the file and couldn’t find anything wrong with columns/rows arrangements, and confirmed it was saved as .csv file, as stipulated.

However, they suggested I made sure it was exported with ‘UTF-8 encoding’’, in order to help ‘properly store characters’. At the same time, the guy is telling me this should be the default encoding in a .csv file. So I don’t know if I can manipulate anything my end with regards to this, and further I don’t see any ‘save as…’ window or drop-down on Numbers for iPad, all saving seems to be automatic with basic ‘export’ options separately, where I already picked .csv from the drop down list.

I’m stuck. Any Ideas?
