Our family hosts a charity Turkey Trot on Thanksgiving. I created a google form for registration which is embedded in our website. There is a point in the form people state the # of shirts they want to order. There is a $15 minimum donation to advance reserve a shirt. I have a field for total amt owed, which the person registering has to calculate (i.e. 3 shirts x $15 = $45) Is there a way to have a formula inserted in the form so the multiplication is done for them, to avoid errors? Just after that is the option to give an additional donation. I'd like to insert a formula to add the total owed for shirts to the additional donation amount.
Sorry for seeming ignorant. I work with excel quite a bit and google spreadsheets and know how to get formulas in the spreadsheets - just don't know how to have it be on the form.
Thanks for your help.
Here is the form link: Feel free to make suggestions on how to improve it. I know it is very rudimentary, but don't have the time to figure out how to finesse it.
