Adding charge (a value) to any selection over the set maximum?

I have a set maximum in checklist of 5. These are inclusive of my base product. How can I allow the customer to select beyond 5 but with a per selection charge?

Do you want to charge your customer if the user selects more than 5? Let me make a demo Form for you. I'll get back to you.

Thanks.

Yes that is correct and thank you.

Here is a workaround for you:

1. I have added a Form Calculation widget in the Form which counts the selection made in your MCQs.

2. Next, added a textbox to store an additional charge that you are going to configure based on the selection of the choices.

3. Add a condition to display the additional charge. For example, if product choice is greater than 5 then $10 would be added. If product choice is greater than 8 then $20 would be added.

Here is the Demo Form:

Let us know if you have further questions.

Thanks.

I've followed your instructions, what am I missing? 

I understand the conditional logic part but I can't get the sum of selections to appear in 'calculation'.

Oops, I think I spotted my error.

Thanks for the update and glad to know that you have sorted the issue. Do let us know if you come across any other issue.
