Hi MV,

Sorry, that you can't get it in the way you want it.

I can't see any option to overcome the widely discussed problems via the Interactive Tag.

Yes, there are formulas, as mentioned above, but there is no option to use them, except perhaps via coding. Since code is not allowed in this forum, based on security, that would be a case for the Developer Forum. But the Developer forum is not a "request-code-delivery-forum", AFAIK.

What you try to do will not work in the way you want it, from my point of view.

At this point, please contact tech support to get a second opinion.
