Woops! You didn't select a marketplace to crosslist to.

1. Go to a listing you want to crosslist and click the extension icon in the top right.
2. Select the marketplaces you want to crosslist to. (If you don't select a marketplace you get redirected to this page)
*Note: If your computer has low RAM you may have to re-select the marketplaces from the drop down each time you crosslist a new listing.  
3. Click the crosslist button and it'll start crosslisting!
