Field Notations in Forms

[escher]

I have used the Simple field notation: TotalListPrice-Discount. Nothing shows up in the Net Before Tax Field.

I have also tried   event.value=this.getField("TotalListPrice").value-this.getField("Discount").value;   and nothing works.

What am I missing? I do not know anything about Java script.

Thanks

Duplicate post. Error in field name used in the script to create the field object.
