I use nutrition data.com. I imputed the items as listed on the mock danish, but I guess there is always room for error

I listed the 4 grams of dietary fiber, but didn't deduct it from the overall carb count.
So NOW I am wondering myself about the carb count in a tsp (1 packet) of splenda. I just looked it up and it says there are 0 carbs in one packet

So maybe that's where the extra carbs come into nutriton data's calculating??????
