How do I set up a prompt so that it causes a passage link to appear when put in correctly?

Question

Twine 2.2.1, Harlowe 2.1.0.

So far, (this is a new story) I only have one variable setup in startup, which is supposed to allow the player to go to that website (because the story I'm making is about the Internet). The site, called www.lkmn.com, is hinted towards in the main passage, and it should be easy to get to. When I put in the site name correctly, it prints what I put in as I hoped, but in the area where the URL is supposed to show, it doesn't do anything. My "home page" has this code:

Current page: https://www.google.com/home
[[Reload->https://www.google.com/home]] | (link: "Enter URL")[(set: $url to (prompt: "What site do you want to head to?","www.example.com"))(print: $url)]

(link: "Search")[(set: $search_bar to (prompt: "What do you want to search?","searchexample"))]

Welcome to your personalkmn homepage!

Is the URL correct? Then it will appear here!
(if: $url is $lkmn)[ [[www.lkmn.com]] ]

The link it's supposed to go to has nothing so far, and the startup only has this (as of the time I write this question):

(set: $lkmn to "www.lkmn.com")

I'm not sure how to fix this issue.

Answer 1

The Target Passage Name part of both Markup based links and macros like (link:) can only reference a passage within your project.

You will need to use the (open-url: ) macro combined with a macro like (link:) to achive the effect you want.

(link: "Reload")[
	(open-url: "https://www.google.com/")
]
