I am in a bit of a pickle here.
I added a new version for my app as I added IAP to it. I've added the IAP item in the "Manage In-App Purchases" menu in the new version section. However I forgot to select the IAP item to be added in the New Version "View Details" page. So I rejected the binary hoping the option to select the IAP item to reappear. But no it does not appear anymore. All it says is:
In-App Purchases cannot be added to this version because it has already been submitted for review. To manage your In-App Purchases, go back to the App Summary page and click on the Manage In-App Purchases button.
So what to do now?
