[thelist] Invalid JS Link

Hi all,

I am building a site in xHTML 1.0 Transitional. The pages all validate,
except for this link:

<a
href="http://www.streetmap.co.uk/streetmap.dll?Postcode2Map?code=OX4+2SU&title=Edmund+Gibbs+Location+Map&nolocal=X">

Which throws up errors like:

cannot generate system identifier for general entity "title" reference not
terminated by REFC delimiter reference to external entity in attribute
value cannot generate system identifier for general entity "nolocal"
reference not terminated by REFC delimiter reference to external entity in
attribute value

How would I go about fixing this sort of thing?

Thanks in advance,
