Splitting a payment between payment methods

Q: How do I enter part of the payment as cash and part by credit card?  When I try to enter the partial payment amount it gives an error message.

A: You need to enter the partial payment in the "Amount to pay" box, not the "Amt Tendered" box.  For instance if they pay $50 by cash and put the rest on credit card, then first enter a Cash payment with $50 in the "Amount to pay" (delete the default value shown there and enter 50).  Note: In more recent versions, you can also enter it in the Amt tendered and then just "OK" the warning that appears.  Now click Payment again to enter the second part of the payment, and the amount to pay will automatically reflect the new balance to be paid by another method.
