I am doing a monthly subscription and using Pagefly as the subscription app. Sometimes my boxes will have clothes in them so I want to ask the potential members what sizes the wear so it will stay with their customer information and I am using form fields in the Pagefly app and also I have the product button for the subscription on the same page but I keep getting this error.
How do I fix this and still be able to keep my form fields the customers fill out?
Sorry, I meant that Pagefly is the landing page. Paywhirl is the subscription app.
For third party issues contact that third party.
General troubleshooting:
If there’s a subscription option on the page, or as the main form etc, then a ~ selling_id is needed.
Implementation will vary WILDLY among apps/services/themes and or combination thereof being used.
