Dear Ngene team,

I have problem with my pivot design.

It is with my attribute price. Because it is a pivot design, the level for price is [-10%; -5%; 0; 5%;10%].

Problem: the reference point is not fixed because people pay different price. So for me, my reference point is 1 (100%)

Can Ngene do ...

Problem is solved!

Thank you.
