# Link up "View Cart" button

You might want to update or add existing *View cart* buttons or links in your current theme. Most typically this would be the little cart icon that usually lives in the menu or header of your theme.

Follow these steps to open the integrated Firmhouse cart when a *view cart* button is clicked.

First you need to locate where your Cart button is loaded in. Typically this will be in `header.liquid` of your Shopify theme.

Then make sure to add the following `onClick` handler to your button:

```html
onclick="Firmhouse.showCart()"
```

Also make sure that the `href` is set to `#` so that the button will not fall back to the standard Shopify cart.

Here's how it should look like:

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.firmhouse.com/sdks/storefront-js-sdk/shopify/link-up-view-cart-button.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
