I wrote this script to get the parameters 
from the query_string:

Call the script...
<MVDO FILE="parsequery.mv"  NAME="IGNORE"
VALUE="{parseNV(query_string)}">

=== parsequery.mv - begin cut ===
<MVFUNCTION NAME="parseNV" PARAMETERS="PARSE_STRING">
<MVASSIGN  NAME="PARSE_STRING" VALUE="{ query_string $ '&' }">
<MVASSIGN  NAME="RESULT" VALUE="{ 'OK' }">
<MVASSIGN  NAME="COUNT" VALUE="{1}">
<MVWHILE EXPR="{(RESULT NE '') AND (COUNT LT 30)}">
         <MVASSIGN NAME="RESULT" VALUE="{gettoken(query_string, '&',
COUNT) }">
         <MVIF EXPR="{RESULT NE ''}">
                 <MVASSIGN NAME="varname"
VALUE="{gettoken(RESULT,'=',1)}">
                 <MVASSIGN NAME="varvalue"
                        
VALUE="{decodeattribute(gettoken(RESULT,'=',2))}">
                 <MVIF EXPR="{ varname NE ''}">
                         <MVASSIGN NAME="{'g.' $ varname }" VALUE="{ 
varvalue }">
                 </MVIF>
         </MVIF>
         <MVASSIGN NAME="COUNT" VALUE="{ COUNT + 1 }">
</MVWHILE>
</MVFUNCTION>
=== end cut ===

You just have to call that function at the top of a page that uses GET 
variables and they are set properly.
