title: Option Set Text value duplicating....is there a property that I can check to avoid duplicating?
body: <p>I have a custom option set on an Opportunity form and one of the option (last) is hidden. I've have a ribbon button &amp; on click of that button I need to show and select that option. It's working fine for the first time but my problem is if I click on that button for 2nd or 3rd time and so on it's duplicating/adding the same text part of that option to that option set...<a href="http://i.stack.imgur.com/rleh8.png" rel="nofollow">Option Set</a></p>
