Missing Conversion Value in Google Ads

Hello Team

we installed their extension Google Tag Manager for Woocommerce, it’s awesome! Thanks very much.

Google Analytics 4 is set up, now I should set up Google Ads correctly, but I’m stuck with the “Conversion value”.

When I test it with Google Tag Manager, I always get the value “0” and there is also no value listed for the conversion tag in Google Ads.

The number of conversions is available but the value is missing.

Is anyone able to help me?
Thank you very much.
