Error reporting an error which is NOT

I have this line in my HTML5 page:

<link href="
https://fonts.googleapis.com/css?family=Simonetta:400,900,400italic,900italic&subset=latin,latin-ext&effect=shadow-multiple"
rel='stylesheet' type='text/css'>

The error reporting tool is giving me these errors:


   1.

   *Error*: & did not start a character reference. (& probably should have
   been escaped as &amp;.)

   At line 20, column 91

   talic,900italic*&*subset=latin,l
   2.

   *Error*: & did not start a character reference. (& probably should have
   been escaped as &amp;.)

   At line 20, column 114
