when I do some Practice about the client variables, have meet this error
Requested scope CLIENT has not been enabled
searchForm.cfm
you can solve this mistake by do this
put this code in your application.cfc file
<cfset THIS.clientmanagement="yes">
also you can do the following:(this is another method)
check your settings in CF Admin -> Server Settings -> Client Variables
<!---
Filename: SearchForm2.cfm
Created by: Nate Weiss (NMW)
Please Note Maintains ÒlastÓ search via Client variables
--->
<!---
When user submits form, save search criteria in Client variable
--->
<cfif isDefined("FORM.searchCriteria")>
<cfset CLIENT.lastSearch = FORM.searchCriteria>
<cfset CLIENT.lastMaxRows = FORM.searchMaxRows>
<!--- if not submitting yet, get prior search word (if possible) --->
<cfelseif isDefined("CLIENT.lastSearch") and
isDefined("CLIENT.lastMaxRows")>
<cfset searchCriteria = CLIENT.lastSearch>
<cfset searchMaxRows = CLIENT.lastMaxRows>
<!--- if no prior search criteria exists, just show empty string --->
<cfelse>
<cfset searchCriteria = "">
<cfset searchMaxRows = 10>
</cfif>
