Hi all,

I have created report in axapta with many data sources.

1. When i open the report, the data not display in report although  data is 
exist in database. The code are :
display FormLetterTxt formLetterRemarks ()
{
    ;

    while select formLetterRemarks where formLetterRemarks.FormLetter==61
    {
     element.execute(1);
    }

    return formLetterRemarks.Txt;
}

Is there any mistakes in my code? cause only this code not display any data.

2. how to use method that i already create
for example : i already create method 'A', and i want to use method 'A' in 
method 'B'. how to call the method 'A' in method 'B' code?

Please help me cause i'm newbie in axapta.
