Using a Constant Sum Total in Skip and Display Logics

The first question in my survey is a constant sum question where the total automatically calculates and displays at the bottom. Then throughout the survey, I would like to apply the following logics based on the total from that initial constant sum question:

(immediately after the constant sum question)
Skip a few questions ahead in the survey if the constant sum total = 0

(later throughout the survey, some examples include:)
Display a question only if the constant sum total was = 2 or 3
Display a question only if the constant sum total was greater than 3
Display a question only if the constant sum total was greater than 1

However, when I go to set up the skip and display logics, the only options are with the specific items in the constant sum question, not the total. Can someone please help me figure this out?

Thank you very much!
