**SunbridgeInstitute**How to set up so one calculation overrides another

Hi there, support team. I am the one with the looming deadline of today, frantically trying to work out all my issues so that I can launch this form after a month of hard work. I have one further problem that is probably too advanced for me to figure out on my own, and I'm hoping you guys can solve it for me.

I have 2 different sets of calculations on my form. Ben helped me work it out so that my "course combo" discounts are working well. This is when there are 2 courses chosen, and one of them qualifies for a discount with the purchase of a full-price course.

The other kind of discount I have is when a person gets a percentage off the whole tuition. This discount should happen to the exclusion of the other discounts. That is, the user can't combine both types of discounts.

I have a field called "Alumni/Community Discount" which is supposed to capture the amount of the percentage discount AND zero out any other discounts that have otherwise been calculated (which are showing just above this one).

Is there a way to accomplish this?

Thank you so much!

**Mike**I would like to suggest trying the following condition on your form. It seems to be working fine on my test form.

You may also want to disable an Autofill option on form to avoid possible side effects.

Thank you.
