Having a problem with my vending machine constantly changing several columns to $325.12, and making them unable to use - saying 'Make another selection'. This happens every 1-2 days after I reprogram it back to the correct dollar amounts. Any ideas??
Thank you very much!

jbiccum,
You might want to check the battery on your controller board, it could be dying, low voltage will make it screw up.
Also programming can be tricky you might want to double check the programming manual we have it here: http://www.vend-resource.com/book/national-gpl-snack-machine-set-and-pro...
hope this helps,
