I have a report on Crosstab in crystal report.
I had two columns Earnings and Deductions.
For Earnings and Deductions had sub column based on it .
There is Earning Subtotal and Deduction Subtotal.
There is column for grantotal in it shows summation of these subtotals
instead of that i need Earning Subtotal - Deduction Subtotal in grandtotal.
I had attached format of report in excel and my design page image.
Please help if u knows about this.
