Easier way to read multiple values selected from 6 list boxes on a coldfusion form

***BELOW IS A SNIPPET OF THE RESULTS FORM TAHT IS BASED OFF OF SINGLE VALUE SELECTED ON MAIN FORM***
<CFIF '#form.listreq#' is "Value 1">
<CFQUERY NAME="results" datasource="datasource">
select * from table where lower(fieldname) like lower('Value 1')
</CFQUERY>
<CFELSEIF '#form.listreq#' is "Value 15">
<CFQUERY NAME="results" datasource="datasource">
select * from table where lower(fieldname) like lower('Value 15')
</CFQUERY>
</CFIF>
 
------------------------------------------------------------------------I know I can satisfy the multiple values selected by doing the same as above but adding more values to the <CFIF> statement:
 
<CFIF '#form.listreq#' is "Value 1, Value 5">
<CFQUERY NAME="results" datasource="datasource">
select * from table where lower(fieldname) like lower('Value 1, Value 5')
</CFQUERY>
<CFELSEIF '#form.listreq#' is "Value 15, Value 20">
<CFQUERY NAME="results" datasource="datasource">
select * from table where lower(fieldname) like lower('Value 15, Value 20')
</CFQUERY>
</CFIF>
 
But since there are 21 total values to select from within the 6 list boxes, I would have to write the code on the results form to display results for one value selected, 2 values selected, 3 values selected, 4 values selected, etc. That would be alot of <CFIF> statements. Is there an easier way to read the multiple values selected within 6 list boxes?
