title: Pinescript: Use text variable in Alerts
body: <p>I wish to include a text variable in the alertcondition.
  I am using <code>alertcondition(scr_label!=&quot;&quot; ,title=&quot;1.Screener ALert&quot;,message=&quot;Screener Alert:&quot;+scr_label)</code></p>
  <p>Here scr_label is a dynamic text variable and I want the alert to give me that as the alert message. However if fires an alert without any message.</p>
  <p>How can I achieve this?</p>
