Gotcha, yeah it might help if i explain what I'm trying to achieve. I'll lay it out by what cells are what.

AE2: current price (this is a number value cell)
AI2: profit per unit at current price (this is a number value cell)
AJ2: promotional price (this is a formula cell)
AK2: promotional profit per unit (=AI2-(AE2-AJ2) (formula cell)
AP2: absolute value of promotion price/promotional profit per unit (=abs(AJ2/AK2)) (formula cell)

I'm trying to find what the minimum AJ2 would be that would give me an AP2 that is greater than 5 (5 at a minimum). AJ2 has to be greater than 0 (since it's a selling price) and has to be less than AE2 since it's a promotional price.
