cannot see problem with my dataAdapter insert statement

[fguihen]

visual studio is telling me that there is something wrong with my insert command for this data adapter and keeps throwing an error when i try to insert a

 

row. can anyone see any problems with this code? the error simply says there is a problem with the insert into statement, but i cant see any problems.

in the table, all fielts are text fields( as it is an access database) except the "text" field which is a yes/no field.

 

this is the code to create the insert command for the data adapter:

this.daContact.InsertCommand = conn.CreateCommand();
		this.daContact.InsertCommand.CommandText = "insert into contact_details(patient_id,home_phone,mobile_phone,address,email,text) "+
												

"values(@patient_id,@home_phone,@mobile_phone,@address,@email,@text)";
		this.daContact.InsertCommand.Parameters.Add("@patient_id",OleDbType.VarChar,50,"patient_id");
		this.daContact.InsertCommand.Parameters.Add("@home_phone",OleDbType.VarChar,20,"home_phone");
		this.daContact.InsertCommand.Parameters.Add("@mobile_phone",OleDbType.VarChar,20,"mobile_phone");
		this.daContact.InsertCommand.Parameters.Add("@address",OleDbType.VarChar,120,"address");
		this.daContact.InsertCommand.Parameters.Add("@email",OleDbType.VarChar,120,"email");
		this.daContact.InsertCommand.Parameters.Add("@text",OleDbType.Boolean,1,"text");

 

here is the code that creates the row that will be inserted:

contactRow = ds.Tables["contact_details"].NewRow();
			contactRow["patient_id"] = guid;
			contactRow["home_phone"] = this.txthomePhone.Text;
			contactRow["mobile_phone"] = this.txtMobilePhone.Text;
			contactRow["address"] = this.txtAddress.Text;
			contactRow["email"] = this.txtEmail.Text;
			contactRow["text"] = this.chkText.Enabled;

			ds.Tables["contact_details"].Rows.Add(contactRow);
