[solved] Purchasing Windows QCAD 3.31.2 issue

I have decided to purchase QCad on the web store and it will not let me use US dollars. It stays locked in to EUR and gives the message “Multiple currencies not permitted in one cart”. I only have one cart and one selection as USD but it does not carry into the cart as such. How do I purchase this software? I am using Windows 10 but this appears to be an issue in the web store.
I have attached a screenshot.

Emty the cart (set QTY to 0), Check out,
Go back to product page,
Choose your Currency (USD)
choose product,
put it in the cart / check cart / if correct Check out …

Thanks…that worked.
