JasperReports' iReport - generating a grand total

Question

Answer 1

Just create a new variable and in the variable expression add up all of the subtotals using their variable name

for instance:

$V{subtotal1}+$V{subtotal2}+$V{subtotal3}

After that, throw it in the 'summary' band and in the report properties check the box that says "summary on new page". That way it'll be on the last page of your report.
