Changing Currency also triggers Exchange Rate to change, so it's possible your function could work as a Post Source instead, however it should work perfectly fine as a field change function. You can add alert('name=' + name); to the beginning of the function call and that will display which fields are triggering the field…

Hi Andreea, Can you try adding the field To Ship On?

It should be already available for the report I'm not 100% sure but I think that it's the same field as ship date since it's matching the dates on our orders
