Add in app purchase with the app on apple developer portal

I am working on an app, in which I have added in app purchase. When I try
to add that in app purchase with the application then I am getting
following message.

But I didn't submit the application, Its current status is "Waiting for
Upload".
I want to add 3 types of In-App-Purchase with the application. What should
I do now ?
Please help me guys.
