can't get HTML using cURL

So in my little app, there is a text field where the user enters a web page and a button that when clicked calls cURL, gets the html and puts it in a text view. For some reason the cURL wont get through and Im getting a

Heres the code

on clicked theObject

		set theHTMLSource to the result
