Forward/Point a Domain to a shopify collections page

[robinette]

Hello: 

Currently I have all product collections on the following parent site, robinettestudio.com.

One of the product collections pages that is under this parent site, needs a domain forward. So that when a visitor goes to jujudollart.com, they will land on the new parent site page location of this product collection and not the old web site.

I'm in the process of deactivating the jujudollart.com web site (this site hosting ends in the next week) but I am having no success in forwarding the domain (jujudollart.com) after working with Go daddy and they have assisted with updating all the forwarding dns info. 

The collection page url:  https://robinettestudio.com/collections/juju

Domain to be forwarded to this collection page: jujudollart.com

Is there another way I should be handling this? Either via code or an app? 

Thank you advance!
