You can tell Salesfire how to find the basket value on the page by providing a Selector.
A Selector is a browser feature that allows websites to find certain elements on a web page.
For example, a Selector may look like:
#basket .total .GBP
Once you have got the Selector for your basket value, you can enter it under Preferences > General within your Salesfire Dashboard.
You can add multiple Selectors and it will look at each one until it detects the first one on the page.
Please provide us some details so we can get in touch and we'll have a chat.
