Trouble with third step of challenge

I just keep getting a "Replace Plant Type with the information from your database" message. I believe I've done this. Am I making an error somewhere?

app.py 
from models import db, Plant, app
from flask import render_template, url_for, request, redirect


@app.route('/')
def index():
    plants = Plant.query.all()
    return render_template('index.html', plants=plants)


@app.route('/form', methods=['GET', 'POST'])
def form():
    if request.form:
        new_plant=Plant(plant_type=request.form['type'], plant_status=request.form['status'])
        db.add(new_plant)
        db.commit()
        return redirect(url_for('index'))

    return render_template('form.html')


if __name__ == '__main__':
    app.run(host='0.0.0.0', port=8000)
models.py 
from flask import Flask
from flask_sqlalchemy import SQLAlchemy


app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///plants.db'
db = SQLAlchemy(app)

class Plant(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    plant_type = db.Column(db.String())
    plant_status = db.Column(db.String())
form.html 
{% extends 'layout.html' %}

{% block content %}
    <form action="{{ url_form('form') }}" method="POST">
        <label for="type">Plant Type:</label>
        <input type="text" name="type" id="type" placeholder="Plant type">

        <p>Plant Status:</p>
        <label for="good">GOOD</label>
        <input type="radio" name="status" id="good">
        <label for="ok">OK</label>
        <input type="radio" name="status" id="ok">
        <label for="bad">BAD</label>
        <input type="radio" name="status" id="bad">
    </form>
{% endblock %}
index.html 
{% extends 'layout.html' %}

{% block content %}
    <h1>Our Plants:</h1>
    {% for plant in plants %}
      <div>
          <h2>{{ plant.type }}</h2>
          <p>{{ plant.status }}</p>
      </div>
    {% endfor %}
{% endblock %}

Mat Clark You are super close! The column names of type and stats in the model are actually plant_type and plant_stats. So if you change stats to plant_stats and type to plant_type, you will be good to go!

Ah, that did the trick. Thank you!
