sql - Column Unknown Firebird Python

Question

I'm trying to make a GUI with python and tkinter for a firebird database. When I try to write the input from boxes into the databse, I get error

fdb.fbcore.DatabaseError: ('Error while preparing SQL statement: - SQLCODE: -206 - Dynamic SQL Error - SQL error code = -206 - Column unknown - NUMBER - At line 1, column 99', -206, 335544569)

This is the code for the submit operation:

simnumbber = "SIM NUMBER"

def submit():

    #  Database connection in the function
    conn = fdb.connect(
    host='localhost', database='C:/SIMCARDS.fdb', user='user', password='password')
    # Cursor
    cur = conn.cursor()
    
    
    # Insert Into table
    cur.execute("""INSERT INTO table ("NUMBER", simnumbber, "OPERATOR", "TYPE", "TARIFF", "DATA", "STATUS") VALUES (:number, :simnumber, :operator, :type, :tariff, :data, :status);""",
    {
        'number': simnumber.get(),
        'simnumber': cardnumber.get(),
        'operator': operator.get(),
        'type': type.get(),
        'tariff': tariff.get(),
        'data': data.get(),
        'status': status.get()  

    })

    # Commit Cahanges
    conn.commit()
    # Close connection
    conn.close()

    # Clear Textboxes
    simnumber.delete(0, END)
    cardnumber.delete(0, END)
    operator.delete(0, END)
    type.delete(0, END)
    tariff.delete(0, END)
    data.delete(0, END)
    status.delete(0, END)

Leaving this here for anyone that has to do something like this. The problem was with the parameters I provided in the SQL query in the VALUES clause. Firebird didn't know what ':number' was. So the fixed query is this:
cur.execute("""INSERT INTO cards (number,"SIM NUMBER",OPERATOR,TYPE,TARIFF,DATA,STATUS) VALUES (?,?,?,?,?,?,?);""", (simnumber.get(),cardnumber.get(),operator.get(), type.get(), tariff.get(), data.get(), status.get()))
