No such column sqlite ошибка

This is a very basic question and I know there are security issues with this code and it should be using parameterized entries among other issues — it is a work in progress. I am attempting to set build a user registration module for a project. I have set up a table with with the first column serving as an ID with a primary key constraint but when I run the code, I get the following error and am not sure why — (if it relates to the p_ID column):

Traceback (most recent call last):
  File "user.py", line 72, in <module>
    userSignUp()
  File "user.py", line 68, in userSignUp
    c.execute("INSERT INTO People VALUES(userName, password, confirmPassword,   firstName,lastName, companyName, email, phoneNumber,addressLine1, addressLine2, addressLine3, zipCode, province, country, regDate)")
sqlite3.OperationalError: no such column: userName

The code is:

import sqlite3
import datetime


path = "/Users/workhorse/thinkful/"
db = "apartment.db"

def checkAndCreateDB():
    #not checking for some reason
    #fullPath = os.path.join(path, db)
    #if os.path.exists(fullPath):
    #   print "Database Exists"
    #else:
    connection = sqlite3.connect(db)
    print "Creating database"
    createUserRegTable()

def createUserRegTable():
    with sqlite3.connect(db) as connection:
        c = connection.cursor()
        c.execute("""CREATE TABLE People
        (p_ID INTEGER PRIMARY KEY AUTOINCREMENT,
        userName TEXT NOT NULL UNIQUE,

        print "table made"

    regDate = datetime.date.today()
    print regDate

    #userInfo = (userName, password, confirmPassword, firstName,lastName, companyName, email, phoneNumber,addressLine1,

    with sqlite3.connect(db) as connection:

checkAndCreateDB()

userSignUp()

Much thanks

I have a table (trackedinfo) inside my database that has the following columns (columns obtained by running PRAGMA table_info(trackedinfo);)

The problem is that even though the column sendok exists, when running a query on the database with that field, it throws an error.

Example queries:

SELECT * FROM trackedinfo WHERE sendok IS NULL;
SELECT sendok FROM trackedinfo;

Error:

SQLITE_ERROR: SQL error or missing database (no such column: sendok)

But, if I run a query selecting all of the fields, it brings me the info regarding sendok:

Here is the CREATE command of the database:

CREATE TABLE trackedinfo
(
    id INTEGER PRIMARY KEY,
    date_time_start TEXT,
    date_time_end TEXT,
    tracked_name TEXT,
    tracked_origin TEXT,
    tracked_maker TEXT,
    tracked_version TEXT,
    tracked_type TEXT,
    sendok TEXT,
    tracked_id TEXT
);

It also happens with the column tracked_id

Info that I got by executing .schema trackedinfo

CREATE TABLE IF NOT EXISTS "trackedinfo" ("id" INTEGER PRIMARY KEY, "date_time_start" TEXT, "date_time_end" TEXT, "tracked_name" TEXT, "tracked_origin" TEXT, "tracked_maker" TEXT, "tracked_version" TEXT, "tracked_type" TEXT, "sendok " TEXT, "tracked_id " TEXT);
