ConfiForms: How to evaluate a CheckboxGroup

[Thomas Bröker]

I have set up a checkbox group (field 'options') where a user can select one of the two or both options. If one of the options is selected a price of '10' shall be shown in the field 'price'. If both options are selected a price of '15' shall be shown.

I am not sure how to set up this configuration. I have tried several 'ConfiForms Rules for Field Definition' according to the different possible options. But then the price field in the end shows "10 10 15".

When I use a formula field the result is only calculated when the form is saved. But the result shall be shown before saving the form.

What is the appropriate way to approach this problem? @Alex Medved _ConfiForms_

Thanks a lot Alex. Then my approach was actually correct. Just my conditions where not right.
