So, I am having a problem with the URL box always saying that I have to match the requested format.

And yes I am putting it correctly with no extra spaces.

It would be helpful to know what you're trying to change it to

to the game page or the page to the speedrun page: https://www.speedrun.com/wind-up_racing https://barji.itch.io/wind-up-racing

???

i tried both to see if it works with either

So what did you try changing it to?

the game page and the speed run page

There can’t be dashes in the URL so it can be:

wind_up_racing

windup_racing

Or something like these
