How to Sum only if field is non blank?

[danny42yu1]

I'm new to Adobe LiveCycle, I am trying to create a table that can sum the amount only if Product Number / Invoice Number is non blank. Please advise on to put together in FormCalc or JavaScript.  Thanks.

Hi

Can you send your example form

From what I can see from your picture it looks like to need to sum all instances of the table rows if column 2 is not blank.

Is this correct?
