Errors made while converting from the plt style

This code charts an app's weekly downloads. Mistakes crept in while it was being converted from the plt style to the fig, ax style, and now it stops with an error when it runs.

Fix two lines so that the code draws a line chart with the title Weekly app downloads, the x-axis label Week, and the y-axis label Downloads.

Code to fix

import matplotlib.pyplot as plt

weeks = [1, 2, 3, 4, 5, 6]
downloads = [120, 180, 150, 240, 300, 280]

fig, ax = plt.subplots()
ax.plot(weeks, downloads, marker="o")
ax.title("Weekly app downloads")
ax.xlabel("Week")
ax.set_ylabel("Downloads")
plt.show()
