Hey Bill, I’m not quite sure what the formula is trying to accomplish but I see a couple potential improvements.
If you’re trying to check if the result of the ROUND() is 0, you want to use `Round(x)==0` instead of `ROUND(x)=0` since the later is setting the value and not comparing values
Round only takes in a single argument, so the 0 is not doing anything. It’s rounding the first value and ignoring the second.
