  1. are you calling msaccess db from fastreport directly? or push data from .net code to fastreport?
  2. what datatype you're using? float, double, decimal? float is less precision
  3. make sure that you've 2 decimal places in the msaccess data, what kind of field type?

  Hi ipong,
  
  ?°) I'm calling msacces directly from fastreport (except that I pass the connection string thru the 'parameters')
  ?°) i'm using Number ('double' with 2 decimal places)
  
  here is a screenshot of the msaccess designer for the fields.
  
  thanks for trying to help me,
  sincerly,
  Domi.

  do not use floating point (float and double datatypes) for accounting records!
  
  msaccess => use currency datatype
  mssql => use money datatype
  
  
  why?

  Thanks for your links but that doesn't work ! I have replaced all the Double with Currency (in my ms database) and I get the same result :

  have you refreshed datasource? check your frx file with notepad:
  
  make sure debit and credit with 'System.Decimal' datatype

      <MsAccessDataConnection Name="Connection" ConnectionString="rijcmlqoDWEBRlB24atBGpA/h9/NbwdWKfjN0xexwR499WDO0y7IJqtWaFegHY0F1Ho9V3Fl2kdv07imQ17CfhEkp1BNgqLT3fvMk7zv9YAiakHxLY=">
        <TableDataSource Name="tbUser" DataType="System.Int32" Enabled="true" TableName="tbUser">
          <Column Name="id" DataType="System.Int32"/>
          <Column Name="name" DataType="System.String"/>
          <Column Name="password" DataType="System.String"/>
          <Column Name="Debit" DataType="System.Decimal"/>
          <Column Name="Credit" DataType="System.Decimal"/>
        </TableDataSource>
      </MsAccessDataConnection>

  Hi,
  
  yes a refresh was made, removed completely the DB and add it back to be sure
  
  here is the def :
  

        <TableDataSource Name="Lign" DataType="System.Int32" Enabled="true" TableName="Lign">
          <Column Name="CleLIGN" DataType="System.Int32"/>
          <Column Name="MVTS" DataType="System.Int32"/>
          <Column Name="NUMC" DataType="System.String"/>
          <Column Name="LIBE" DataType="System.String"/>
          <Column Name="DEBI" DataType="System.Decimal"/>
          <Column Name="CRED" DataType="System.Decimal"/>
  ...
  
      <Total Name="TotalDebit" Expression="Lign.DEBI" Evaluator="Data1"/>
      <Total Name="TotalCredit" Expression="Lign.CRED" Evaluator="Data1"/>
  ...
  
        <GroupFooterBand Name="GroupFooter1" Top="138.85" Width="718.2" Height="37.8">
          <TextObject Name="Text17" Left="481.95" Top="9.45" Width="217.35" Height="18.9" Text="Solde : [[TotalDebit]-[TotalCredit]]" />
        </GroupFooterBand>
  

  
  
  BUT
  
  
  I have added 'Format="Currency"' in the xml :
  

          <TextObject Name="Text17" Left="481.95" Top="9.45" Width="217.35" Height="18.9" Text="Solde : [[TotalDebit]-[TotalCredit]]" Format="Currency" >
  

  
  and the format is like expected which is strange because the TextObject doesn't contain only numbers but also text : "Solde : TotalDebit]-[TotalCredit"

  have you solved 0.0012999..... ? if not, i think there is something wrong in your data
  you may check with creating 'running sum' with code.
  
  use currency formatting only if solved

  As you can see in my last post/printscreen, the display is now correct (2 decimals) after added Format="Currency" in the field containing the substraction but I don't know if it's the right way or not to solve this
