Javascript document.write %20 problem

I have this code <SCRIPT LANGUAGE="JavaScript"> [login to view URL]( getQueryVariable("ww") ); </SCRIPT> that is not working correctly for me. Or I have messed up the data later on. This above code is in an html file named [login to view URL] I have an html file named [login to view URL] that sends a link to [login to view URL] This works from when the keyword is only one word like "keyword" but when keyword such as "new keyword" is loaded via [login to view URL] keyword it shows up as "new%20keyword" can someone please tell me how to fix this. I can show you the rest of the java script which is just one small snippit if needed, how ever if I could change the above javascript and make it work this would be great.
