Clearing up a cash->receipt error

["Roderick A. Anderson" <..hidden..>]

While blundering my way through getting last years invoices into LSMB I 
made an entry via cash->receipt for an invoice I'd entered.

Now I have this minus "Amount Due" for the customer and not sure how to 
clear it up, i.e. get rid of the credit.  Should I enter the amount as a 
plus or minus?
