Built app with Flash Builder 4.6 and compiled for iOS, now error when loading to appstore

I built a fairly simple app using Flash Builder 4.6 and have successfully deployed it to the Android Market (after testing on my own Android device).  I have also taken that same app and compiled it for iOS and tested it on my own iPad. 

I have then done the release build with the "Final Release for App Store Distribution" option in the release build wizard.  I have all the correct provisioning certificates in place and compiled the application to a .ipa file.

At this point, using a MAC, I have run the Application Loader utility to upload my application to the itunesConnect portal to get it in the appstore.  I've already gone through the steps of entering the metadata, price scheme, and screenshots in the itunes connect portal, and just need to upload it for review.

When I upload the .ipa file into the application loader, it gives me the following error:

"iPhone/iPod Touch:  application executable contains unsupported architecture(s): arm"

Anyone have any idea what this means and how I can fix it?  Any help is greatly appreciated!

Thanks in advance!
