Error Parsing Query: [ Token Line Number = 1,Token Line Offset = 83,Token In Error = 5 ]

Hey all-

I'm trying to insert some values into an SQL Compact database on a WM6 device but there is something apparently wrong with my SQL statement...

The program is going to allow users to schedule an SMS message to be sent at a certain date and time. I'm using a database to keep track of the scheduled SMS messages. The database has 3 rows: phone number, message, and the date/time to be sent.

Here is the relevent code:


private void scheduleMenu_Click(object sender, EventArgs e)

{

//connect to DB and do our scheduling magic



string message = messageBox.Text; //should rename messageBox...

string phoneNum = phoneNumBox.Text;



string dataBase = @"Program FilesSMS_Scheduler2SMSDatabase.sdf";

//SqlCeEngine eng = new SqlCeEngine(dataBase);

SqlCeConnection conn = new SqlCeConnection("Data Source=" + dataBase);

conn.Open();



//insert phone number, message text, and date/time into DB
string cmd = "INSERT INTO Scheduler(phoneNum, message, date) VALUES("+ phoneNum + ", "+ message + ", "+ dateTimePicker1.Value +")";

SqlCeCommand cmdPhone = new SqlCeCommand(cmd,conn);





cmdPhone.ExecuteNonQuery(); //error occures here...



messageBox.Text = "";

MessageBox.Show("Message Scheduled!");

}



I'm guessing it doesn't like how I am trying to get the data from the different text boxes and the DateTimePicker to go inside the SQL command. Does anyone have any ideas on how to fix my SQL command or how to get data from a textbox and DateTimePicker to be inserted into a database a different way?
