Hi,

how to use the feature of the subscription is described in detail in the documentation.

www.vi-solutions.de/en/documentations/cu...eld-type-calculation
and an example here
www.vi-solutions.de/en/documentations/cu...-a-simple-order-form

And instructions on how to set up your forms and fields individually are not part of the subscription but basically what you have to do is the following:

You have to create three fields of type number or text in your form (adults, children, aged) with the field names adults, children and aged. If you choose the field type number make sure that "Digits only" is checked. Set a default value of 0 for the fields and if you use the number type you can set a minimum value of 0, too.
In the calculation you simply have to write [ADULTS] + [CHILDREN] + [AGED]

Exactly what we need.

Tnx a lot!
