Web application designer issue

Question

hi expets,
i have a template which has three drop down boxes,a table and a chart, when i select only the first two i should pass the url to query1,and when i select all three then i should be able to pass the url to query2,query3,etc depending upon the value i select in the third drop down, i am passing the filter values(drop down values) as an url(url1:="<SAP_BW_URL DATA_PROVIDER='*' multi="X" FILTER_COLLAPS=' '>)and i am concatinating the filter and its values to that string for the first case.for the second one i need to pass the values to a particular query(url2:'<SAP_BW_URL DATA_PROVIDER='DATAPROVIDER1' CMD='RESET_DATA_PROVIDER' INFOCUBE='infocubexx' QUERY='query1'>)the query1 changes depending upon the value i choose from the third drop down box,eg if i chosee a value 2 it would be query2, i tried to concatinate the filter values to second url but it gives me error can u let me know how to pass the filter values to a particular query depending upon the selection.
and what is the difference between the following two:
1):="<SAP_BW_URL DATA_PROVIDER='*' multi="X" FILTER_COLLAPS=' '>)
2)<SAP_BW_URL DATA_PROVIDER='DATAPROVIDER1' CMD='RESET_DATA_PROVIDER' INFOCUBE='infocubexx' QUERY='query1'>).
thanks in advance.
