Hello there, hope you're well, i'm trying to build a formula that can calculate two rates commission based on est.gross profit, as one of our reps is going onto a different rate and want to keep the calculation in one column, it's been a while since i've tackled formulas and have come up with the one below, but showing as an invalid expression, (i've used a false name for the rep!). I'd appreciate any advice on whether this is completely wrong or if there's an easy fix so that the two differing rates show in the same column, thanks for
