LiveCycle Simple Calculation

FormCalc provides a function called "Sum()" that can sum individual fields or an array of fields. The exact code depends on the layout and field names. So if you have the extension of the "qty" and "price" field into the "total" field for fields in the same subform and the form is not dynamic, the calculation for the "subtotal" field can be:

Sum(total[*])

Which is to say sum all the fields named 'total". You will not that capitalization and spelling of the field name is critical.

You can also create an example purchase order form from the supplied templates and review the scripts in the created form.

You can also look at the "Scripting Reference" provided under the "Help" menu option of LiveCycle Designer.

Thanks for your answer. I did what you said and I still have the message (Accessor....unknow).
My table is as follow. 7 columns and around 10 rows.

1) Quantity - Unit Price - Total
My first calculation is ok (Total: Sum(Quantity*UnitPrice)

The second calculation, to calculate all the total sums in the last column does not work at all.
