why isnt my skannerz working
i printed the healing bar code off barcode mill, and the instruction guide but my skannerz isnt reading them
ive printed them off the internet and had them work before

Best answer:

if u want to heal ur monsters go down 2 heal on the menu and then when it says scan scan the barcode that came on the instructions
