i have a huge project i am working on and I will need to use countif and sum
if for a lot of the cells in the summary page

1. Do count if and sum if work the same way except one counts instances and
one sums the cells?

2. if I use the formula helper, is the range the part that I want counted
or added up?
3. If is use that helper and I need to have several conditions met for this
to be added up or counted how do I input my conditions?
