# Setup stuck on “waiting for tracking data”

> What to check when a test lead isn’t being detected.

This step is waiting for a **lead submission** from a page running your snippet. If it's stuck, no qualifying submission has been detected yet.

## Fixes

1. **Submit a test lead** on a page that has the snippet — use one of your real forms with a test email.
2. **Check for an iframe form.** By far the most common cause is a form embedded in an iframe with the snippet only on the parent page. The snippet needs to run **inside the form** too. See [snippet placement](/getting-started/where-to-place-the-snippet).
3. **Use the same session.** Start the visit and submit the form in the same browser window without clearing cookies in between.

When a lead is detected, this step completes and syncing begins.
