Algorithm to check the cross of the matrix

Algorithm to check the cross of the matrix using
where  m_matrix is an object of the IVSFlexGrid wrapper.
for (int i = 2; i < pGrid->GetRows(); ++i)
{
   if ( dLamount[i] > 0 && dHamount[i-1] > 0 )
   {
     double dAmountDifference = 0.0 ;
     damountDifference = dLamount[i] - dHamount[i-1];

      if ( damountDifference > 1 )
     {
        CString strMessage;
         strMessage.Format("Difference in the amount", damountDifference );

      if (IDYES == ::MessageBox(GetSafeHwnd(), strMessage, "", MB_ICONINFORMATION MB_YESNO))
      {
               return true;
}
else
{
     return false;
}
}
}
}
