Ive been trying to lsit an item on my laptop, i have tried creating my own listing as well as sell similar from anothers listing.  

I offer free shipping however whenever i click  free shipping, it clears everything back to adding into dimensions, so i add that, and nothing happens, i click i dont know the package details, it brings up the options, to choose your postage serive, i do that, Australia post Domesric, it auto populates that buyer pays, even if i add $1 it then reverts back to an error, postage needs adding.  If i click it to free postage, again it goes through the above.. im so damn frustrated about now lol..
