Redirecting subdomain to external landing page

I’ve been going round and round and need some help. I’ve built a landing page in unbounce.com and they tell me i need to create a subdomain on shopify and point it to their site. I created get.deborahwildebooks.com but I can’t figure out how to redirect it to unbouncepages.com. It says its redirecting to deborahwildebooks.com.

Then after a bunch of circular logic, button mashing and steam from the ears, I got to the point where i created what is highlighted in the attachment. Which i would guess is the specific page on unbounce that needs to be targeted but this doesn’t seem to be configured correctly either.

Any help would be appreciated.

Because I couldn’t leave well enough alone. I may have figured it out. Will test in the morning…

Did you find a solution?? I’m having the same problem! My Unbounce page worked last night (I even signed up for my offer) and mysteriously stopped overnight!!

If your page was working it may be a different issue. I did find that I was creating the subdomain incorrectly. Instead of clicking the button that says “create subdomain” I should have followed this…
