And if you expect your list to ever be shorter than your desired subset, you
could dynamically set your "to" attribute using the iif function so you
don't error out:
<cfset variables.list = "0,1,2,3,4,5,6,7">
<cfloop from="1" to="#iif(listlen(variables.list) gt 3, DE('3'),
'listlen(variables.list)')" index="i">
<cfoutput>#listgetat(variables.list,i)#</cfoutput><br>
</cfloop>
Although that might be overkill for your situation. You will probably want
to verify my syntax as well, it's probably wrong.
