Rather than display the first value of each group in the group header, the report is easier to navigate if it displays the credit limit range for each group, as follows:

This procedure shows how to write a JavaScript expression to display these credit limit ranges. The procedure also shows how to create a column binding with which to associate the JavaScript expression.

New Data Binding, shown in Figure 8‑9, prompts you to create a column binding for the new data element.

Figure 8-9 New Data Binding

Figure 8‑9
On New Data Binding, provide a name and expression for the column binding. Use the default data type, String.

for(i=50000; i<300000; i+=50000){
if( row["CREDITLIMIT"] < i ){
rangeStart = i-50000;
rangeEnd = i-1;
displayString = rangeStart + " - " + rangeEnd;

Select the data element. In Property Editor, under Properties, choose General, then choose B to format the group heading as bold text.
