Error-No value given for one or more required parameters when using oleDBDa

Question

Hello,
I have this sql statement and it works well, the Crystal Report gives good result when I put concrete values like:
string comstring = "SELECT NOVI.GBR as gbrnov, NOVI.AB as abnov, NALOG1.DATA as datanov, Min(NALOG1.POCKM) AS MinOfPOCKM, Max(NALOG1.KRAJKM) AS MaxOfKRAJKM, (Max(NALOG1.KRAJKM)-Min(NALOG1.POCKM)) AS RAZLIKA, Count(IIf(([MAGACIN.SIFRA]='0991000'),[MAGACIN.KOL],Null)) AS Gorivo, Avg(IIf(([MAGACIN.SIFRA]='0991000'),[MAGACIN.KOL],Null)/100) AS potrosgor100km, Sum(IIf(([MAGACIN.SIFRA]='0993050' Or [MAGACIN.SIFRA]='0993051'),[MAGACIN.KOL],Null)) AS Motmaslo, Sum(IIf(([MAGACIN.SIFRA]='0992201'),[MAGACIN.KOL],Null)) AS Addblue, ([Addblue]/[Gorivo])100 AS Addbluegor, Sum(IIf(([MAGACIN.SIFRA]='0999001'),[MAGACIN.KOL],Null)) AS Antifriz, NOVI.DATAP, NOVI.DATAS, IIf(([NOVI].[KM]<=([NOVI].[KMS1][NOVI].[KMS2])),'ZA SERVIS',(IIf(([NOVI].[KM]<=([NOVI].[KMP1][NOVI].[KMP2])),'PROVERKA',''))) AS Zabeleska FROM (NALOG1 INNER JOIN NOVI ON NALOG1.GBRV = NOVI.GBR) INNER JOIN MAGACIN ON NOVI.GBR = MAGACIN.GBR where (((NOVI.GBR)>='1001' And (NOVI.GBR)<='1080') AND ( ((NOVI.AB)='AK') OR ((NOVI.AB)='AK') ) AND ((NALOG1.DATA)<=#10/31/2011# and (NALOG1.DATA)>=#10/31/2011#) ) GROUP BY NOVI.GBR, NOVI.AB, NALOG1.DATA, ([Addblue]/[Gorivo])100, NOVI.DATAP, NOVI.DATAS, IIf(([NOVI].[KM]<=([NOVI].[KMS1][NOVI].[KMS2])),'ZA SERVIS',(IIf(([NOVI].[KM]<=([NOVI].[KMP1][NOVI].[KMP2])),'PROVERKA','')))";          
but when I use code like this :
string comstring = "SELECT NOVI.GBR as gbrnov, NOVI.AB as abnov, NALOG1.DATA as datanov, Min(NALOG1.POCKM) AS MinOfPOCKM, Max(NALOG1.KRAJKM) AS MaxOfKRAJKM, (Max(NALOG1.KRAJKM)-Min(NALOG1.POCKM)) AS RAZLIKA, Count(IIf(([MAGACIN.SIFRA]='0991000'),[MAGACIN.KOL],Null)) AS Gorivo, Avg(IIf(([MAGACIN.SIFRA]='0991000'),[MAGACIN.KOL],Null)/100) AS potrosgor100km, Sum(IIf(([MAGACIN.SIFRA]='0993050' Or [MAGACIN.SIFRA]='0993051'),[MAGACIN.KOL],Null)) AS Motmaslo, Sum(IIf(([MAGACIN.SIFRA]='0992201'),[MAGACIN.KOL],Null)) AS Addblue, ([Addblue]/[Gorivo])100 AS Addbluegor, Sum(IIf(([MAGACIN.SIFRA]='0999001'),[MAGACIN.KOL],Null)) AS Antifriz, NOVI.DATAP, NOVI.DATAS, IIf(([NOVI].[KM]<=([NOVI].[KMS1][NOVI].[KMS2])),'ZA SERVIS',(IIf(([NOVI].[KM]<=([NOVI].[KMP1][NOVI].[KMP2])),'PROVERKA',''))) AS Zabeleska FROM (NALOG1 INNER JOIN NOVI ON NALOG1.GBRV = NOVI.GBR) INNER JOIN MAGACIN ON NOVI.GBR = MAGACIN.GBR where (((NOVI.GBR)>=? And (NOVI.GBR)<=?) AND ( ((NOVI.AB)=?) OR ((NOVI.AB)=?) ) AND ((NALOG1.DATA)<=? and (NALOG1.DATA)>=?) ) GROUP BY NOVI.GBR, NOVI.AB, NALOG1.DATA, ([Addblue]/[Gorivo])100, NOVI.DATAP, NOVI.DATAS, IIf(([NOVI].[KM]<=([NOVI].[KMS1][NOVI].[KMS2])),'ZA SERVIS',(IIf(([NOVI].[KM]<=([NOVI].[KMP1][NOVI].[KMP2])),'PROVERKA','')))";

Answer 1

and the code after that:
command.CommandText = comstring;
            if (radioButton4.Checked == true)
                if (textBox1.Text == "")
                    button1.Enabled = false;
                    MessageBox.Show("Внесете гаражен број", "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                    textBox1.Focus();
                    command.Parameters.AddWithValue("@gbr1", textBox1.Text);
                    command.Parameters.AddWithValue("@gbr2", textBox1.Text);               
            else if (radioButton5.Checked == true)
                command.Parameters.AddWithValue("@gbr1", "1001");
                command.Parameters.AddWithValue("@gbr2", "1080");
                button1.Enabled = true;
                textBox1.Text = "";
            else if (radioButton6.Checked == true)
                command.Parameters.AddWithValue("@gbr1", "1081");
                command.Parameters.AddWithValue("@gbr2", "1149");
                button1.Enabled = true;
                textBox1.Text = "";
            else if (radioButton7.Checked == true)
                command.Parameters.AddWithValue("@gbr1", "1001");
                command.Parameters.AddWithValue("@gbr2", "1149");
                button1.Enabled = true;
                textBox1.Text = "";
            else
                MessageBox.Show("Немате избрано гаражен број или тип на автобус.", "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                button1.Enabled = false;
            if (checkBox1.Checked == true && checkBox2.Checked==true)
                command.Parameters.AddWithValue("@ab1", "AK");
                command.Parameters.AddWithValue("@ab2", "GP");
                button1.Enabled = true;
            else if ((checkBox1.Checked == true) && (checkBox2.Checked == false))
                command.Parameters.AddWithValue("@ab1", "AK");
                command.Parameters.AddWithValue("@ab2", "AK");
                button1.Enabled = true;
            else if (checkBox2.Checked == true )
                command.Parameters.AddWithValue("@ab1", "GP");
                command.Parameters.AddWithValue("@ab2", "GP");
                button1.Enabled = true;
            else
                MessageBox.Show("Немате избрано автобаза.", "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                command.Parameters.AddWithValue("@ab1", "AK");
                command.Parameters.AddWithValue("@ab2", "GP");
                button1.Enabled = false;
            command.Parameters.AddWithValue("@data1", dateTimePicker1.Value.Date);
            command.Parameters.AddWithValue("@data2", dateTimePicker2.Value.Date);
             DataSet2 dataSet2=new DataSet2();    
             OleDbDataAdapter oleDBDataAdapter1 = new OleDbDataAdapter();
            oleDBDataAdapter1.SelectCommand=command;
                dataSet2.Clear();
                oleDBDataAdapter1.Fill(dataSet2,"Tabela");
                if (dataSet2.Tabela.Count == 0)
                    MessageBox.Show("Nema podatoci za toj period");
                ReportDocument cryRpt = new ReportDocument();
                cryRpt.Load(@"C:\Potrosuvacka-Pregledi\Potrosuvacka-Pregledi\CrystalReport6.rpt");
            cryRpt.PrintOptions.PaperOrientation = CrystalDecisions.Shared.PaperOrientation.Landscape;
                cryRpt.SetDataSource(dataSet2);
                crystalReportViewer1.DisplayToolbar=true;
            crystalReportViewer1.ReportSource = cryRpt;                      
            crystalReportViewer1.Refresh();
                conn.Close();
I get an error:
"No value given for one or more required parameters."
Could anybody help me please?
Thank you in advance.
