Hi all, 

I am either  using a different version of this software or going crazy!!!

Is there a difference between the UK and the USA version?  We call it credit note in the uk not memo.. but for this difference aside I cant see none of those in my UK version : 

1. Select Receive Payments.
2. Choose the customer on the Customer:Job ▼ dropdown.
3. Click on the Apply Existing Credits? checkbox.
4. Hit Save
