@phevos thanks for saving my bacon! I did my calculation ignoring the .44 mg/l already present in my aquarium and that is how I got the wrong answer. Taking that into account I get the correct number.
Thanks again!!!

By the way - I wasn't criticizing your calculator. I have never sent an ICP - nor dosed trace elements. My coral (when I had it) - ate the same food as the fish.Yeah, that's what I thought--I had done two 25% changes in the month before I sent the test in (tank is small, so there's no reason not to), so when I got the results back and saw that some of the more important traces were zero, I started fishing around the forums. Got sidetracked and made the calculator.
