& in links

I have a link like this (see below) where i have replaced the '&'
signs with '&amp'
<a href="http://www.klm.com/travel/gb_en/index_default.html?popup=no&amp;adcamp=sea.KLMDestinationsEU&amp;adchan=sea.google&amp;adtype=searchad.EUBulgaria&amp;adctry=gb&amp;adlang=en&amp;stlcmpid=10342#"
target="blank">

But I now recieve another error instead of the one telling me to
change the '&' signs
The error I now get is: "The entity name must immediately follow the
'&' in the entity reference."
