iOS Question In-app purchases, best practice

I found further information. It seems that modifying settings to turn off ads is the solution; therefore, 1 app. However, what do I sell in the app Store? I need a product Id. I don't see any option to create such an id as to accomplish this.

You should start with iStore - In App Purchases

Thanks; but that was my first stop. My question is what "product" do I create in the Apple Store? Is it the SAME product ID as the app that contains the ads? Logically, it can't be so, since the ad filled app is free in the store. Removing the ads is not a problem in the free app. What product do I select in the app store to create for purchasing (the Ad-Free version)? From what I've gathered, it is NOT another AD_FREE app. This is a non-consumable product. In the app Store, from what I can see it means adding ANOTHER app (ad free). I see no "upgrade option" in the store, so to speak.

I also have an app with advertising.
To remove the advertisements I use the option "In-App-Purchses" with "non-consumable product".
So that the user can also install the app on a second device, I create a GUID license code with the purchase date and save it in a database so that I can check next time whether the user has paid for it.

I've already done that in the store. Maybe the app store uses the same product id. That must be why it asks for the price.

I've followed all the instructions to the best of my understanding. I'm stuck with this error.
I've created sandbox account; have app set up in store; added test in-app purchases. I'm logged into my device as sandbox user (I have not visited store).
I'm using the sample code without modification other than the ID (which seems to be the issue)

What am I doing wrong?

This is my error:

The only thing that we can say is that the product id is probably wrong.

Solved: Issue was that the wrong Bundle Id was selected in the General Information Section of the App Information screen.
