I am just about to add the event code a button that downloads the pdf.
Event code fields: _trackEvent(category, action, opt_label, opt_value, opt_noninteraction)
Example of event code: onClick="_gaq.push(['_trackEvent', 'Videos', 'Play', 'Baby\'s First Birthday']);"
I was just wondering if anyone knows if there is a text limit on the opt_value?
Do you think the following would be too long 'Elmhurst School says IPC has made all the difference'?
