Smarty and custom field question

[rookers]

Hello,

I have created a custom field called RSS, so site owners who have RSS syndication on their site can publish their rss feeds on their detail pages in my directory. Now my question is this: is there a smarty statement or instruction that will allow to display nothing if a site owner doesnt enter any rss feed url? Because right now, when no rss feed url is specified i get this message : Warning: parse_url(http://) [function.parse-url]: Unable to parse url - because the field is empty.

Would appreciate your help! Thanks!

Using the follow it will only display the RSS field if there is data

<% if $RSS%>
<% $RSS%>
<% /if%>
