If i understand correctly, the above ISL always shows $8 saved in all transactions.
How can this be linked to all availed discounted amount in the transaction.
Also i don't need this to be printed if a discount is not in the transaction.
The $8 is actually just defining the maximum length, not the value. Nothing over 8 digits will work - the SIM will error out. As this script stands it will always display 0.00 as he didn't put in code in to actually add up the total discount amount.
