My current CS Project using the water saving fixtures and saving the water up to 36% Reduction and our project will used the gray water from waste water treatment plant for all the flush fixtures which will give our project 77% Water saving. I typed my calculation with the used of grey water in the flush fixture attached to Alternative Compliance Path and select to get ID credit with Exemplary point on WEc3 but some how when I tried to click complete the form on WEc3, it does not allow and show me the warning about "The credit has threshold options and cannot be completed unless at least one option is selected." What should I do. Thank you.
