First CFC question

Question

Ok, I'm working on my first CFC, and having some problems.
The code I have
so far is:
<cfcomponent displayname="duplicate" hint="Duplicates
local club
tournaments">
<!--- This function retrieves all customers from the
database --->
<cffunction name="getinfo"
hint="Gets all tournament info from the database">
<cfquery name="DuplicateTournamentList"
datasource="SalleBoise">
select * from clubtournaments
where TournID=#session.tid#
</cfquery>
<cfset NewEventName=DuplicateTournamentList.TournName>
<cfset NewEventDesc=DuplicateTournamentList.TournDesc>
<cfset
NewDateTime=dateadd("m",2,dateformat(TournDateTime,"mm/dd/yyyy"))>
<cfset
NewTournFoil=DuplicateTournamentList.TournFoilEvent>
<cfset
NewTournEpee=DuplicateTournamentList.TournEpeeEvent>
<cfset NewType=DuplicateTournamentList.EventType>
<cfset
NewDuplicate=DuplicateTournamentList.TournDuplicated>
<cfquery name="NewTourn" datasource="SalleBoise">
insert into clubtournaments
(TournName,TournDesc,TournFoilEvent,TournEpeeEvent,EventType,TournDateTime,TournDuplicate d)
values
(#NewEventName#,#NewEventDesc#,#NewTournFoil#,#NewTournEpee#,#NewType#,#NewDateTime#,#NewD uplicate#)
</cfquery>
<cfquery name="UpdateOldTourn" datasource="SalleBoise">
update clubtournaments
set TournDuplicated=1
where TournID=#session.tid#
</cfquery>
</cffunction>
</cfcomponent>
And I'm calling it with:
<cfinvoke component="duplicate.cfc" method="getinfo">
And I'm getting:
Error Occurred While Processing Request
Could not find the ColdFusion Component or Interface
duplicate.cfc.
Ensure that the name is correct and that the component or
interface exists.

The 1 question I have with your code that is different than
mine is the
query. Mine, I had hoped would take the info from the
previous event,
and add a number of months to it before adding it into the
table.
It looks like yours simple duplicates the event without
changing that
date, correct?
