Simple calculation

Hello,

well, if I’ve understood, I think there is no problem doing what you ask, simply:
Create a new form, call it as you want.

Add one CHECKBOX, selecting it and drag and drop on right menu, title it, ID it with A
“value for checked” = 10
“value for unchecked” = 0

Add another one CHECKBOX, title it, ID it with B
“value for checked” = 20
“value for unchecked” = 0

Add another one CHECKBOX, title it, ID it with C
“value for checked” = 30
“value for unchecked” = 0

Add a OUTPUT, title it, ID it with SUM
“formula” = A+B+C
“unit before number” = € or $
“leading zero” = 0
“decimals” = 2

Go to Generals copy and paste on your article or page the Jazzy code.

Done?

My Jazzy Form under the name of the fruits (in Italian sorry): https://www.condifesa.ra.it/calcola-il-preventivo/

I must be doing something wrong, cause all I get in the output field is “invalid formula”.
I have checked “Update output elements instantly” under general.

The ID of my output field is SUM
and the formula is =A+B+C

The checkbox fields are also as you mentioned.

you can see it here:

This is how I configured it: my form

The fields B and C are configures as A part from the “value when checked”.

Hello!

Solution is simple!
Just remove the “=” on formula field… “A+B+C” is enough.

Try it and let me know…

Thanks!
It turned out to be something in the theme (headway) as well.
It works fine in twentytwelve.

Thanks again for your help!
