Customer display siemens Ba63 seriell

Question is:

I have followed this link from Forum to set up my Display. Banner and ItemsTemplate are working well.They are showing correctly, but Pole Total template shows me wrongly. I need only Total that customer has to pay and need to show to customer how much he is getting back.

Total: 65.–
Due: 5.-

[LAYOUT]
<R> 
<J>Pd:{TENDERED TOTAL}| Chg:{CHANGE TOTAL}
<R>Total: {TICKET TOTAL}

Any rule is missing in this link?
