Hello.
We are looking to start using search bars in the headers of our emails so a customer can type in their local town and on click, it takes them through to the website of the closest site to them, see below.

However, we're having an issue with the tracking breaking - if tracking is disabled for this link it works perfectly but if tracking is kept on the link it does not work and a 'requested URL cannot be found' error message is displayed.
The below script is used in the HTML for the search bar to pull in what the customer inputs but it appears the GA tracking doesn't like it when applied and breaks. To note, the 'abcd' in the below is just for illustrative purposes.
<form action="https://www.abcd.co.uk/abcd/" method="get" name="search_form" id="search_form">
Any ideas on how I can get this functionality to work but with the tracking enabled?
Thanks.
