Syntax error with xvfb start

Hello, i try use test server. And have some problem with XVFB
I add script, after i try start have this:

root@gb:/# chmod +x /etc/init.d/xvfb
root@gb:/# update-rc.d xvfb defaults
update-rc.d: using dependency based boot sequencing
root@gb:/# /etc/init.d/xvfb start
/etc/init.d/xvfb: 24: /etc/init.d/xvfb: Syntax error: word unexpected (expecting "in")

Change #!/bin/sh to #!/bin/bash

And after i have this:

root@gb:/home/asqatasun-4.0.0.i386# /etc/init.d/xvfb start
/etc/init.d/xvfb: line 24: syntax error near unexpected token `start'
/etc/init.d/xvfb: line 24: `start)'

How fix? On board Debian.
