Hi Niki,
One simple question: Are you sure you're creating the LOV and Parameter IN the Data Foundation Layer (DFX)? That's critical. You've attached pics of the LOV and Parameter which is great, can you also attach a pic to prove that you've created them in the Data Foundation Layer?

I assume, you may have created LOV and Parameter in the Business Layer (BLX), rather than the Data Foundation Layer (DFX). If that is the case, "you can't use something before it actually exists," the LOV and Parameter have to exist in the Data Foundation Layer, to be able to use them in Derived Table. Because, DFX is the source for BLX and not the other way around.
Thanks,
