Hi Jason,

I want to generate a report with cumulative.

I am creating the report using Cross tab.

The report is like,

jan || Feb || Mar
1 || 2 || 3

1 is the value of Jan and 2 is the value of Feb and 3 is the value of Mar.

for Jan, the value is same.
For Feb, The report should calculate jan+ Fab

i.e

Jan || Feb || Mar
1||3||6

Plz help me on this.

On the aggregation element in the crosstab put an oncreate script like:

//This is summing integers, you can also use parseFloat
if( typeof myrunningsum != 'undefined'){
myrunningsum = parseInt(this.getValue()) + parseInt(myrunningsum);
}else{
myrunningsum = parseInt(this.getValue());
}
this.setDisplayValue(myrunningsum);

See attached example

What is the data type of the element and what version of BIRT are you using.
