How do you import an IIF file with a tax only credit memo. i was able to import an invoice, but the same setup for a credit memo does not work.  If i use the tax group it says the item is the wrong type. if i use the tax items it says i have an invalid reference to the tax item. I tried the "i'll fix it later" link but that just says it is an invalid transaction. 

I'm attaching a file with an example of each. Maybe i'm missing something.

-Thanks in advance.
