Workflow Action Script Alert

Hi All,

I have a workflow action script which is running a search actioned via a Workflow button, I want to display an Alert that shows the count of results in the searchresults array but the usual 'alert' command doesn't work.

Any suggestions how I can display this after the button press please.

if (searchresults != null)          {          alert = ('There Were' + searchresults.length + 'User Testers Found');           }      else           {          alert('There Were' + searchresults.length + 'User Testers Found');           }
