How to output 2 values ​​from Shopkeepr to the header?

Question

MODX

Recently started working with this cms. Tell me, you need to display information in the header how many purchases a person has now and the total cost. How can I connect the shop keeper to the header chunk in order to pull out only this information. These are two variables [+price_total+] [+currency+]. I stick in the [!Shopkeeper!] code and change the chunks_ShopCart.tpl template, leaving only these two variables there. But it doesn't work. Tell me what I'm doing wrong.
PS: Installed modx 2 days ago.

Answer 1

[+price_total+] [+currency+] - this is the price and currency, to display the number of goods, [+total_items+] is used.
