I want to add a link that would show up in the header when someone is logged in if they have an order with an open balance to pay.
Currently if there is a balance, when you are logged in and viewing an order, there is a link to pay.
I want to have that display in the header when logged in. If there any orders with a balance, then nothing would display.
So it would display text like "Order #11111 has a balance, click here to pay". When they click they go to payment page.
Any thoughts on how to do this?
