I can not change my Steam URL on my account that got lost?

I can’t even change my Steam URL after adding funds?

Go to Steam and expand. You should be able to change your Steam Trade URL.

I am not able to for some reason. I will post a screenshot if wanted.

If you’re getting an error, the screenshot would definitely help identifying the problem.

Here is the image.

Hey, please see the instructions on how to update the Steam Trade URL below.

To update your trade URL go to the Gameflip main menu > Settings > Steam connect. Please note that you can only use the URL to the Steam account linked to Gameflip. We do not have the ability to unlink Steam accounts at this time.
