I'm trying to track how many visitors click on a button in our site. The problem is the button is located within an iframe coming from an external service.
Here is the page in question: http://www.anoisewithin.org/support-us/individual-giving/#tabs-7
I would like to be able to measure how many visitors click the Search button in the iframe, but I am unable to append any Google Analytics tracking code to the button. Is there any other way I can track that particular click event?
