Memberstack Webflow expert

I'm new to webflow and memberstack but i got signed up. I need some help getting the basics in place. I want to use this common template i have it installed here - [login to view URL] I want the user to choose a plan and signup. i got this kinda working but cant seem to bind the plan on signup. but ideally the flow is choose a plan, signup and pay. then you are a customer. then it would be really helpful to setup base dashboard that is tied to a specific customer. [login to view URL] then i can probably hack around from therebut getting the basic in place will help us figure out how all of the data bindings work. one other note. i want to sell one-time buckets of credits and not monthly recurring. so when they are signing up they need to choose one of the credit buckets and also once they are a member i need them to be able to buy more credits... is this also something you can help with? i was thinking each time they buy a bucket of credits we can just keep adding that amount to a custom field that increments and I can use that same field to figure out if they need to buy more Integromat/make is not a part of this project requirement but am hoping to meet people that might also have that skill so we can use in future features on this site. not required though
