**SunbridgeInstitute**I just made several changes on this form today that are not working out, and so I wanted to revert to the form as it was this morning, but the revision history is not showing anything earlier than 3 weeks ago, and there are also some wierd errors inside those 10 updates made 3 weeks ago. Is there any way that my form can be reverted to the version as it was early this morning before I started making changes?

Thank you!

**BDAVID**I have forwarded this to our back-end team. You will be notified via this thread when the error in the Revision History gets fixed.

**SunbridgeInstitute**Is there any update on this situation? Our form has been down all weekend at a critical time. I am trying to fix the errors myself but everything I try is not working. All that I need is for the calculation to work. It was working before I tried adding in a coupon, and ever since I did that, the calculation is always zero. If they don't know when the revision history will be corrected, can someone at least help me to either remove the coupon so that the calculation works again, or else to incorporate the coupon so that the calculation works?

Thank you!

**Sven**Hi,

We still don't have any update on this, but I can see that it's marked as important. Our developers will get to it as soon as they can, and you will be notified via this thread with the updates.

As for the calculation, I checked your form and it's quite long, so can you please explain the issue that you're having with it? And point us to where exactly is the problem so we can help you with the calculation.Thank you!

**SunbridgeInstitute**Thanks for the help. Most of the fields can be ignored, and I will describe what I'm trying to accomplish with the calculation:

The total in the "Total Cost Calculation" is supposed to be:

1. the number from "I wish to purchase",

2. doubled if there is a second person ("would you also like to register a second person?"=yes)

3. plus the donation amount, if any ("enter the amount you would like to donate")

This part of the calculation seems to be working fine now (I found a mis-coded parens in my formula), but now for the part that I was having trouble with...I'd like to add a coupon, with the code "WAIVE". The amount of the coupon is calculated "I wish to purchase" x2 if there is a second person. The donation amount should remain after the coupon has been applied.

I have set up 2 fields for this: "Coupon Code," and "Discount." I thought I had it all figured out how to use the conditions and calculations, but nothing I tried worked. If you can give me a headstart, I would appreciate it.

Thank you!
