Hi Ljc16,
Welcome to the Support Communities!
The articles below will provide some troubleshooting steps for the trackpad on your Macbook Pro. Do you have a USB or wireless mouse you can use while testing? If you need to restart your computer, you can first save the tabls that are currently open. On the menu bar, click on Bookmarks, then click on "Add Bookmarks for These Tabs."
