Hi @Dawood1 ,
Welcome to the Shopify Community! Thanks for asking a good question in the community.
I need to see your product page why the discounted price is not showing. Could you please provide us your product page URL where the discounted price has, but not displaying on the product page.
@Dawood1 Check in your theme settings then navigate to the Product page within theme settings and see what you have available. It might be as simple as enabling a setting.
Or if it's something that used to show but does not after a recent edit, rollback your theme by either publishing the previous theme before this one, or by going to the file edited and look for a previous version (some theme files are able to rollback to a previously edited version).
Lastly, before editing your theme code or theme settings, always duplicate your theme first and work off the backup theme, so you can preview the changes before publishing and so you have a backup copy of the previous theme state.
