FileExists problems

I am trying to do test to see if a file is in a specific file folder location and if the file exists then it displays the icon to download it.  Here is the code I have so far and I just need a little help to get it going. The part #queryObj2.Video_path# is just part of a query that returns a name in the video_path.  Thanks.

CODE:

<cfset yourFile = "../download/files/powerpoints/"&#queryObj2.Video_path#&".pptx">

<cfif FileExists(yourFile)>

    <p>Your file exists in this directory. You entered the correct filename</p>

</cfif>
