I'm sorry you are having trouble installing the code. Once you've installed the BoostSuite app on Weebly, you need to click the Publish button in Weebly once to take our tracking code live on your site. Then, visit your Weebly site's homepage and click around to a few different pages on your site to begin sending visitor data to BoostSuite.
Then return to your BoostSuite dashboard. The status message at the top will indicate whether or not we're receiving tracking data from your website.
I hope that helps, but if you have any more questions don't hesitate to ask!
