you cant use the % function to award a bonus credit you would need to do taht via the acceptor or use seprate coin inputs
the above credit scheme dont add up anyway 3 for 50p but only 5 for £1 ?
if u have 1 coin on each input its easy to set them to give any credits u like, if you wan to just us 1 input for all coins then just round up (not floating point math) eg 30p becomes 34%
