Problem with PayPal in store

Hi,
I have a problem with PayPal payment in our store.
I have set client id type DGTIU7654 and when trying to pay (click button) I get error message client-id not recognized for either production or sandbox: GDGTIU7654 (debug id: f74475618daa3).
I tried to set email id of paypal account but then I get error Invalid query value for client-id: This email address is being protected from spambots. You need JavaScript enabled to view it.
What am I doing wrong?

Tom
