What plugin are you using for this ? I mean email or form ?

I think you need to use custom query to make it happen.

I think you need to create it Step by step

1. You need to create Members. Who can predict.
2. List of competitor.
3. adding point for wins. (Members/Users) Etc.

I think custom coding can be a good solution for this.

Are you using a premium theme or a custom theme ?

I think you can use a form plugin like Gravity form for this. You can set a default value and user can edit the value and click on save and after that they will get an email.

I have gone through your website and I can see you are using ASTRA with Elmentor. I have gone through the link and I can see the text of the banner is causing the issue Elementor have option to set the font size for mobile. please adjust it accordingly.

Go to settings permalinks check post name and save the changes. Let me know if its solved for your help https://nimb.ws/mLT78x

Try this and let me know if it works

.woocommerce-shop .main-sidebar {
display: none;
}

Thanks a lot.
