Interaction IDs in scormcloud

Hi

I am asking this out of research rather than any dire emergency!

Does anyone know where the Interaction IDs appear in the SCORM cloud reporting data that's collected? I have a 'fully ID-ed' quiz tracking OK.  I can see in the Detailed Activity report which questions the user answered right and wrong but Scormcloud displays the actual questions asked rather than the IDs I assigned. The Captivate Interaction IDs don't appear there and I can't see them in the 'Reportage' section either. If I search the interaction section for my IDs nothing comes back. There's no sign of them anywhere as far as I can see. Is this info kept in another of SCORMCLOUD that you have to pay for.

Any help appreciated!
