Hello Dorin.
This is what I'm doing.
.
.
.
        string lcStr1;
        string lcStr2;
        string lcStr3;
        double lnAmt;
        OleDbConnection concxn = new OleDbConnection(strConn);
        concxn.Open();

        OleDbCommand cmd = new OleDbCommand(strQuery, concxn);
        OleDbDataReader readr = cmd.ExecuteReader();
        while (readr.Read())
        {
            lcStr1 = readr["cust_id"].ToString();
            lcStr2 = readr["Company"].ToString();
            lcStr3 = readr["country"].ToString();
            lnAmt = readr["maxordamt"];
            strQuery = "insert into MyTarget (cust_id, Company, country, orderamt) values ('";
            strQuery += lcStr1 + "', '" + lcStr2 + "', '"+lcStr2+"', '"+lnAmt+"')";
            OleDbCommand cmdx = new OleDbCommand(strQuery, cn);
            int ExcInsert = cmdx.ExecuteNonQuery();
            
        }
.
.
.
C# doesn't like lnAmt = rdr["maxordamt"];.
And I can't do lnAmt = rdr["maxordamt"].ToString();.
How do I save maxordamt, which is a numeric (99999.99) into lnAmt variable so I can insert it into orderamt field in MyTarget table which is also numeric?

Thanks
