Behavior

Error correction level: There are 4 error correction levels used for QR codes, with each one adding different amounts of backup data depending on how much damage the QR code is expected to suffer in its intended environment, and hence how much error correction may be required\:\r\nLevel L up to 7% damage\r\nLevel M up to 15% damage\r\nLevel Q up to 25% damage\r\nLevel H up to 30% damage
{Level L - up to 7% damage | Level M - up to 15% damage | Level Q - up to 25% damage | Level H - up to 30% damage} QRErrorCorrectionLevel

Formula

QR code formula: The formula or expression to calculate the QR code value. String
