Help! Widget showing HTML code as plain text!

Hi! Im trying to do a widget that shows some info in tabs. Everything is working OK but when I add some HTML (img and formatting tags) the widget shows the code as plain text.

I show the content of the widget with a simple echo:
<div id="fragment-1" class="content"><?php echo $aData["35MM"]; ?></div>

And this is how I save changes on the CP options:

if( isset( $_POST['cabeceraListenIn_35MM'] ) )
        {
            $aData['35MM'] = stripslashes($_POST['cabeceraListenIn_35MM']);

            update_option( 'cabeceraListenIn', $aData );
        }

(There are 5 tabs (“fields”) but I only include 1 here for the example).
What Im doing wrong??
