Hello ,
I am coding an MP3 download that basically makes a new folder then goes to the
stored location and copies the mp3 and places it in a new folder that later can
be deleted.  Once the folder is made and the mp3 is in it - the idea then is to
force the download by sending it to a force download script in an iframe ( php
script )
Then re-locate the enduser to an alternate page.

Sounds easy?

The problem - Is that the forceddownload works if the mp3 is already there, so
I am guesing that the code runs too fast and when it gets to the force download
script - the mp3 file has not yet been written. yet  If this is so - how can I
make sure that it is there first and then have it wait until the code is run
before it executes the forcedownload and redirect?

Below is the script I am using - the problem is that  each bit of coding works
seperately but when run together it goes straight to the <cflocation> and skips
the download bit.
<cfset newFold =
replace(getCurrentTemplatePath(),getFileFromPath(getCurrentTemplatePath()),'')>

   
    <cfset newPath= #REReplace(#getSong.SongFileLoc1#,"/","\","ALL")#>
    <cfset mp3Path= #REReplace(#getSong.NewFileLoc1#,"/","\","ALL")#>
   
    <cfset newDir="#newFold##newPath#">
    <cfset MusicDir="#newFold##mp3Path##getTuneVerified.TuneKeyCode#">
   

<p><cfoutput><cfset rootPath =
replace(GetDirectoryFromPath("http://"&cgi.server_name&
cgi.path_info),"\","")></cfoutput></p>
   
    <!--- <p><cfoutput>#newDir#</cfoutput></p>  --->
    <cfset downloadMe =
