[TYPO3] Flashfile in templavoila - local processing xml for the TO?

[Sebastian Schön]

Hello,

in the local processing xml for the TO (input field image) I ´ve the
following TS- Code:

   <TypoScript>
						20 = MULTIMEDIA
					  	20.file = fileadmin/img/728x90.swf
						20.params (
						pluginspage = http://macromedia.com/go/getflashplayer
						type = application/x-shockwave-flash
						quality= high
						width=560
						height=60
						)
</TypoScript>

This works for a static swf file. But I want to insert  the Flash  
file dynamically.

   I try to get the field input into it in the following manner:

   <TypoScript>
20 = MULTIMEDIA
					  	20.file.import = uploads/tx_templavoila/
						20.params (
						pluginspage = http://macromedia.com/go/getflashplayer
						type = application/x-shockwave-flash
						quality= high
						width=560
						height=60
						)
</TypoScript>

This did not work.  Can somebody help me to solve the Problem. Thank´s.

regards
Sebastian
