In the project settings for the page-setup, place the object in the header.

in Step 1 (Settings) i do not see the Page-setup .  could you send a screenshot ?

Like said John

Hello Ramon,
the contents mentioned by John are actually in Step 2 - Template ---> Template Content ---> Header, as shown in Axel's screenshot
You can then add the object called Cart Status.

Dear Eric,

I followed the Steps. but in the categories i cant find the Cart Status. Only User Orders or Product Catalog

Hello Ramon,
please open the object management screen, then refresh the list of objects with the relevant button and use the searchbar to look for the object.
I remain available.

Dear Eric, 

I see that i have to Buy the Cart Status object (12 credits) I will do that and i guess it will appear in the Categories after i bought it. 

Thank you for the help.

...you can do this in Step 3 by dragging the cart from the special pages section in the menu...

ciao

In my demo shop, the shopping cart symbol (free) above (without the additional functions of the paid object) can be copied and inserted into a text object in the header and linked to the shopping cart.
