C# Insert Command Parameter Error Message

[Jonathan Presnell via .NET 247]

I am trying to insert some data into a sql server 2000 databaseusing c#.net. I am getting the following error message:
SQL Error 8178: Prepared Statement ..... expects @Param1, whichwas not supplied.

Here is the code snippet where all the work takes place:

private void btnSave_Click(object sender, System.EventArgs e)
{
int time = 0;

sqlInsertCommand1.CommandType = CommandType.Text;
sqlInsertCommand1.CommandText = "insert into trainingroomdatavalues(@idnum,@dateof,@timeof,@isa mof,@pur)";


sqlInsertCommand1.Parameters.Add(newSqlParameter(" @idnum",SqlDbType.Int,4));
sqlInsertCommand1.Parameters["@idnum"].Value = 0;
sqlInsertCommand1.Parameters.Add(newSqlParameter(" @dateof",SqlDbType.SmallDateTime,4));
sqlInsertCommand1.Parameters["@dateof"].Value =monthCalendar1.SelectionStart.ToShortDateString() ;
sqlInsertCommand1.Parameters.Add(newSqlParameter(" @timeof",SqlDbType.Int,4));
sqlInsertCommand1.Parameters["@timeof"].Value = 4;
sqlInsertCommand1.Parameters.Add(newSqlParameter(" @isamof",SqlDbType.Bit,1));
sqlInsertCommand1.Parameters["@isamof"].Value = 0;
sqlInsertCommand1.Parameters.Add(newSqlParameter(" @pur",SqlDbType.NVarChar,500));
sqlInsertCommand1.Parameters["@pur"].Value = "to hell withthis";

try{
sqlConnection1.Open();
sqlInsertCommand1.ExecuteNonQuery();
sqlConnection1.Close();

MessageBox.Show("The data was successfully entered into thedatabase","Success",MessageBoxButtons.OK);

}
catch (SqlException ee)
{
foreach(SqlError err in ee.Errors)
{
MessageBox.Show("SQL Error " + err.Number + " : " +err.Message);
}
}
finally
{
sqlConnection1.Close();
}

}
I have added test values for the parameters in order to figureout what was going on, but to no avail. If anyone could pointme in the right directon, I would greatly appreciate it. I havesearched this discussion board, but all the previous suggestionshave not worked! Thanks.

Somewhere else on that form, I bet you'll find a Parameters.Add @Param1.
Looks like maybe sqlInsertCommand1 was built by the configuration wizard and
has already added some params. You could loop through the collection and
see if it exists, I'm betting it does.
