You're fine. When you type out a submission as you've done, none of the links are clickable by design. It's conventional for someone to comment with the link as comment links are clickable.
You could have also just submitted the URL alone which would be clickable, but then you wouldn't be able to write your message and your post wouldn't show up on the Ask tab, which is where you want it.
