How can I get the missing amount

Hi peterteszary,

thanks for reaching out.
Yes, you can display the remaining amount by using style 7 of the progress bar shortcode: https://www.wc-donation.com/documentation/usage/progress-bar-shortcode/

And you can add multiple progress bars to your website. I can see that your page does have multiple progress bars already in the HTML although they are hidden by some custom script & styling.

Best,
Jonas

PS: If you’ve found Donation Platform for WooCommerce helpful and would like to support its continued growth and development, I’d truly appreciate it if you could leave a 5-star rating on WordPress.org. Thank you so much!
