2 options in the code replacement for using flash signatures

[Christian]

OK, on UBB we had the option the users could use flash sigs by typing [flash="width","heigth"]url of the movie[/flash].
I want to do that also now in vBulletin.
The problem is that the code replacement only reads 1 option!
For example:

vB Code tag: flash

vB Code replacement: <EMBED src="\7" quality=high WIDTH=\5 HEIGHT=\6 TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash"></EMBED>

vB Code example: [FLASH=200,120]http://www.geocities.com/carailbrubat/Logos/CarailBrubat.swf[/FLASH]

When i do this vb reads as param \6 already the ] so that the height of the movie is 0!
I get the following result then:

[FLASH=200,120]http://www.geocities.com/carailbrubat/Logos/CarailBrubat.swf[/FLASH] is replaced with (<EMBED src="http://www.geocities.com/carailbrubat/Logos/CarailBrubat.swf" quality=high WIDTH=200,120 HEIGHT=] TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash"></EMBED>)

How can I use both params in the first bracket?
