You might be having trouble setting up the listing correctly if you used IE to do it.

You can revise a listing.

Try that, but first, do this when you have eBay open if you're using IE:

tools menu in Internet Explorer, then Compatibility View Settings, add ebay.com.au, ok. The screen will reload and should be OK if you weren't seeing it right/able to do things correctly.

If that still doesn't work, give Chrome a go for setting up listings as it is more eBay friendly.
