Custom report calculation

Hello, I want to make a custom report, where under the total of the user a comission of 9 percent is calculated.
here is my code

` @{REPORT PAYMENT DETAILS:P.User,P.Amount.Sum::{0}:,}

[Settled by $1:1, 1, 1]

{REPORT PAYMENT DETAILS:P.Name,P.Amount.Percent,P.Amount.Sum:(PU=$1)}

Total Income|{REPORT PAYMENT DETAILS:P.Amount.Sum:(PU=$1)}

Comission|[=F(({REPORT PAYMENT DETAILS:P.Amount.Sum:(PU=$1)})*0.09)]`

here is the result:

I don^t get why the result is like that. Can you please help? Thanks.

You need to use a field calculation. I’m not where I can demonstrate but field calculations are demonstrated in our wiki page for custom reporting.

Your report worked fine for me but you may need to use TN function to ensure it handles numbers correctly.

@{REPORT PAYMENT DETAILS:P.User,P.Amount.Sum::{0}:,}
[Settled by $1:1, 1, 1]
{REPORT PAYMENT DETAILS:P.Name,P.Amount.Percent,P.Amount.Sum:(PU=$1)}
Total Income|{REPORT PAYMENT DETAILS:P.Amount.Sum:(PU=$1)}
Comission|[=F(TN("{REPORT PAYMENT DETAILS:P.Amount.Sum:(PU=$1)}")*0.09)]

Thanks a lot no now it works !
