Multiple Select & Concatenation

System

I'm using a multiple select on a DCT that allows the user to specify which Divisions (Human Resource, Information Services, etc) a piece of content is associated with. I'm also printing that information in the output of the presentation template as Keywords for search purposes (ASP Page).

In reference to Knowledge Base Article: 1663, I've implemented that in my TPL. However, when the page is generated, the value are concatenated, rather than deliminated by anything. By default, should they be deliminated by a comma? If not, how can we deliminate them?

DCT CODE:
<select required="t" multiple="t" size="5">

TPL CODE:
<meta http-equiv="keywords"
content= "<iw_iterate list="dcr.MetaData.DivisionKeywords" var="temp">
<iw_value name="temp"/>
</iw_iterate>">

OUTPUT:
<meta http-equiv="keywords" content= "Human ResourceInformation Services">

What I would like to see: <meta http-equiv="keywords" content= "Human Resource, Information Services">
