Need to have different calculated prices per subscription

I’ve added the go cardless widget and it bases the price on the calculation which I understand. However where there are two different prices dependent on the service frequency selected how do I show  different prices on the go cardless link. Ie a price for every 4 weeks and a price for every 8 weeks. 

Please note that you can select from which Form Calculation field you want to get the value for your subscription.

Currently, you only have one calculation field, hence, the Get Price From dropdown only shows you one option.

Simply create another Form Calculation field so you'll now have 2 calculation fields. Then adjust each of the field's calculation so that one is for the 4 weeks subscription and the other one is for the 8 weeks.

After you have successfully setup your calculation fields, modify your subscriptions to Get Price From the correct calculation field.

Hey there thanks for your reply. I did do that however what I found is that when doing that both are shown? So for example if someone clicks every 8 weeks then every 4 weeks will show on calculation form as 0 then someone would click next and the price would show. Then it would go through to go cardless to sign up and price will show 0 for 4 weeks and a price for 8 weeks. I need both prices to show regardless of what frequency customer chooses. And I also really want it to work the calculation out without showing the calculation but putting the price on go cardless. Please help?

If I understand properly, you would like to show both prices for 4 weeks and 8 weeks on the Payment widget; unfortunately, that's not possible since the price is being fed by the calculation widget.

For the Form calculation widget, you can easily make it invisible to your clients by enabling Hide fields on the Form Calculation Properties.
