Hello. I'm currently trying to create a Chrome Extention. I'm trying to make a simple to-do list extension. Everything works, except for the add button. When I click it, nothing happens. No task is added to the list. Can someone help figure out why? It worked for a full HTML page, but Google Extensions don't allow inline javascript. I've tried to change everything over to work, but still no luck. Thank you! ---manifest.json--- { "name": "Task todo list", "description": "Allows user to enter in tasks to a list", "version": "1.0", "manifest_version": 2, "permissions": ["alarms", "notifications", "storage"], "browser_action": { "default_icon": "icon16.png", "default_title": "To-Do List", "default_popup": "popup.html" }, "icons": { "128": "icon128.png", "48": "icon48.png", "32": "icon32.png", "16": "icon16.png" } }
