Help! Google Custom Search Fails W3C Validation

I've just added the Google Custom Search code into my template and plan to insert google analytics code. I ran the page through W3C Markup Validation Service which found 4 errors within the code, I've highlighted the error in red.

Line 33, Column 93: cannot generate system identifier for general entity "t13n_langs"

…m/coop/cse/t13n?form=cse-search-box&[COLOR="Red"][B]t[/B][/COLOR]13n_langs=en"></script>

Code (markup):

Line 33, Column 103: reference not terminated by REFC delimiter

…/t13n?form=cse-search-box&t13n_langs[COLOR="Red"][B]=[/B][/COLOR]en"></script>

Code (markup):

Page was created with a XHTML 1.0 Strict doctype. Page validates perfectly without the google code.

 

Im guessing they dont allow their code to be edited in anyway.

 

I assume so, is it possible to insert the code in a css file?

 

Try to change character & with Entity code: &

...search-box&t13n_langs=en">

change to:

...search-box&t13n_langs=en">

 

Thanks I'll try using the &, hopefully it wont mess things up on google's end.
