Hi Ray.. many thanks for this.
It is possible that I will have to rebuild this as the application system is likely to change so a few questions if I may so hopefully I can then deal with the same issues if they re-occur.
1: When you say form code was to high can you specify what code on what page you are referring to?
2: Where and how would I have created a blank per-item tax field?
3: What code did you have to adjust for the complex pricing issue and where is it located?
