I created my spreadsheet this week by making a copy of the wellness log. I am learning so much about spread sheets. The way I write my formulas is I always start with an equals sign, then I click a cell and I put a operation sign in. I do the same thing with the other cells then it shows you all different data. You should use this data and apply it to your sheet. Another way you can use this is for a different type of log or other data. Spreadsheets are most commonly use to organize data usually numbers.
