I'm attempting to simply 1/2 a total if a preceding field is marked 'yes'.

Summer camp registration and we are giving a 50% to faculty members. I am using the form calculation wizard and have all the fields being added (field 1+field 2+field 3)*.5 is how I have it currently and it is simply returning the total with out the multiplier.

I have checked your account and tried checking your recently edited forms. However, I am unable to find the calculation field. Please provide us with the form ID/URL that you are working so that we can take a look and provide you with necessary assistance.

Thank you!
