If you don’t get any response, then it’s because none of the conditions are true, and it’s going to the red option on the condition.

Try adding a step printing out the values of all variables, and doing the math manually to see what’s happening here.

Also add a message step after the red dot, so that you can check that it’s indeed going there.

Setting this up is not difficult, but you need to be tidy and organized with the numbers and conditions to make sure it works the way you want and that the math adds up.
