If you are shown several options of forms to capture when mapping an external form (see How to capture external forms with Tracking Script (v3)) and you are not sure which form is the one you want to capture you can check with the following steps.
In this example we are looking at https://force24.co.uk/contact and the options of forms provided were as follows.
1. Go to the page with the forms on in your browser
2. Right click on the first input of the form you wish to capture and click inspect.
3. You will be shown the underlying HTML of your site. Look above from your initial position for the form element.
4. Check this element's attributes for it's ID and classes. For example in the above example we can see wpcf7-form and init in its class attribute but no ID.
5. With this information we can see that it matches with the first option 'wpcf7-f1547-p40-o1 form' so we can now select this as the correct form to map.
