Question Using sed with bash variables

Hi Guys

I have another problem I'm trying to solve and hope that some one can help me here.

This is the scenario:

I have a file and I want to add a line on the 3rd line of the file using a bash script. but instead its adding the the bash variable $WEBSITE.

Below is the bash script I'm using.
Code:
#!/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11

echo "what is the website ?"
read WEBSITE
if grep -q $WEBSITE "/etc/squid3/acls/allowed-sites"
then
        echo "$WEBSITE already exists"
else
        echo "adding website $WEBSITE"
        sed -ie '3i\$WEBSITE\' /etc/squid3/acls/allowed-sites
        echo "restarting squid"
fi

I have tried a few different ways of doing this with sed but nothing works.

Please help.

Please wrap all code, files, input & output/errors in CODE tags.
It makes them far easier to read and preserves multiple spaces for indenting or fixed width data

LOGPROF.CONF(5)                                                      AppArmor                                                      LOGPROF.CONF(5)

NAME
logprof.conf - configuration file for expert options that modify the behavior of the AppArmor aa-logprof(1) program. DESCRIPTION
The aa-logprof(1) program can be configured to have certain default behavior by the contents of logprof.conf. The [qualifiers] section lists specific programs that should have a subset of the full ix/px/ux list when asking what mode to execute it using. Since creating a separate profile for /bin/bash is dangerous, we can specify that for /bin/bash, only (I)nherit, (U)nconstrained, and (D)eny should be allowed options and only those will show up in the prompt when we're asking about adding that to a profile. Likewise, if someone currently exec's /bin/mount in ix or px mode, things won't work, so we can provide only (U)nconstrained and (D)eny as options. And certain apps like grep, awk, sed, cp, and mkdir should always inherit the parent profile rather than having their own profile or running unconfined, so for them we can specify that only (I)nherit and (D)eny are the allowed options. Any programs that are not listed in the qualifiers section get the full (I)nherit / (P)rofile / (U)nconstrained / (D)eny option set. If the user is doing something tricky and wants different behavior, they can tweak or remove the corresponding line in the conf file. The [defaulthat] section lists changehat-aware programs and what hat aa-logprof(1) will collapse the entries to for that program if the user specifies that the access should be allowed, but should not have it's own hat. The [globs] section allows modification of the logprof rule engine with respect to globbing suggestions that the user will be prompted with. The format of each line is-- "<perl glob> = <apparmor glob>". When aa-logprof(1) asks about a specific path, if the perl glob matches the path, it replaces the part of the path that matched with the corresponding apparmor glob and adds it to the list of globbing suggestions. Lines starting with # are comments and are ignored. EXAMPLE
[qualifiers] # things will very likely be painfully broken if bash has it's own profile /bin/bash = iu # mount doesn't work if it's confined /bin/mount = u # these helper utilities should inherit the parent profile and # shouldn't have their own profiles /bin/awk = i /bin/grep = i /bin/sed = i [defaulthat] /usr/sbin/sshd = EXEC /usr/sbin/httpd2 = DEFAULT_URI /usr/sbin/httpd2-prefork = DEFAULT_URI [globs] # /foo/bar/lib/libbaz.so -> /foo/bar/lib/lib* /lib/lib[^/]+so[^/]*$ = /lib/lib*so* # strip kernel version numbers from kernel module accesses ^/lib/modules/[^/]+/ = /lib/modules/*/ # strip pid numbers from /proc accesses ^/proc/d+/ = /proc/*/ BUGS
