Javascript fix TODAY dropdown select

NEED THIS TODAY. NEED SOMEONE IMMEDIATELY TO HELP ME WITH A SCRIPT. The way it is written now the end result is something like this _nkw=2014+car1+color1 I need it to result in Screen=SRCH&Store_Code=xxx&Search=2014+car1+color1 In the script there is code like this: (this is part of the code involved but it is the part that needs fixing). <form id="dropdowns_form" name="dropdowns_form" method="get" action="/search?"> <input class="botton" type="hidden" id="nkw" name="_nkw" value=""> and then there is this: var fullquery = srchquery0 + " " + srchquery1 + " " + srchquery2 + ""; [login to view URL] = fullquery; [login to view URL](); The problem is that instead of _nkw I need it to not have that in it, and to have the right search link for the ecommerce program. I have been able to get part of the result I need but it is ascii encoded and I have not been able to get rid of _nkw.
