Unable to view text in my textfield

I am able to rotate my textfield dynamically but my text has disappeared even though i have embeded the font and color.
here is the code

some_tf = new TextFormat();
some_tf.font = “myVerdana”;
some_tf.size = 24;

tfNewfield.text = “here comes the text”;
tfNewfield.border = true;
tfNewfield.embedFonts = true
tfNewfield._rotation = 90;

Please help!!!
Thanks in Advance
