Sum Function Syntax

[naveed]

Hello I have a basic report I am building, there are currently only 3 bands,

GroupHeader
data
GroupFooter

The grouping is configured to be by customer, and each customer has entries with an itemname and weight. I want to put a sum of the weight in the footer per customer but cannot seem to get the syntax correctly.
{sum(DataSource1.weight)} in the footer seems to be what should work, but it isn't - any ideas?

Hello,

Please use the following expression for this:

{Sum(DataSource1.weight)}

Thank you.
