cf10 how do I pass the selected value in cfselect to another .cfm page

I am new with CF. I am using CF 10 on WIN XP. I am pulling a distinct list of data and want the user to select one to open a new page (detail.cfm) and pass that value to the next page to be used for other queries.

can it be done?

Here is my code for cfselect .

What am I missing

<cfform name = "Form" action="detail.cfm"

         <cfselect name="trip"

                    query="gettri"

                 value="district_name"

                 required="yes"

                 multiple="yes"

                size="1">

    </cfselect>

<br> <input type="Submit" value="Submit">

</cfform>

Thank you for your time
