Call a script from more than one button?

I have a need to add 3 buttons to call the same javascript form, when I add more than one instance of the link, they all seem to fail except for the first instance. Is this possible?

<a class="button" href="" id="eventButton">Find out more</a>
<script type="text/javascript" src="http://ift.tt/1w6AKvm" id="gather-loader" data-locationid="7ppyugvm" data-trigger="eventButton"></script>
