Total of WHT

Hello,

I hope that there will be anyone who could help me… My question/concern is how to get the total of WHT & VAT per line (sales line-dynamics nav). Because in my report that I created, I made an entry of 2 lines with wht, but when I preview the report, it splits and create their own total. I want to summarize all the VAT & WHT per line…

please see screenshot.
