I am calculating blood sugars for my daughter and putting them in a spreadsheet. The formula is simple:
Blood sugar - target blood sugar / 20 which yields the amount of insulin that she needs to take. I want this cell to be blank unless I enter a value in the cell above it.
Next, I take the value from that formula and add it to the amount of insulin that she takes for eating.
The value in the top formula can be 0 or less, but, if the value in the bottom one is less than 0, I want the cell to be blank.
I hope someone can give me some help on this.
Thanks.
