# Why is View on the frontend link not working?

In the Form admin, to preview the form on the frontend, use the "View on Frontend" function. This will generate the form's URL in the following format:

```
https://[store_name].myshopify.com/apps/product-registration?form=[form_slug]
```

If you have modified the URL path (e.g., changed `/apps/product-registration` to something else), the "View on Frontend" link will not work. You will need to update the URL to match the new app proxy path.

You can find the app proxy in the Shopify admin by navigating to: **Apps > My Product Registration > ... (top right) > App Proxy**.

If the app proxy is changed from the default, you will need to update the URL to reflect the new format. Ensure that the new URL path matches the updated app proxy path to maintain functionality.

```
https://[store_name].myshopify.com/[app-proxy]?form=[form_slug]
```

If your store uses a custom domain, the URL format will be:

```
https://[your-store-domain]/[app-proxy]?form=[form_slug]
```

or

```
https://[your-store-domain]/apps/product-registration?form=[form_slug]
```

> **Note:** It's not recommended to change the default app proxy, because some of the links will not work out of the box. Weigh the pros and cons before making any changes to the app proxy.
