Initialize file name bash shell - Linux

I am trying to initialize a file name in bash but not having much luck. For example, one of my bash scripts outputs a file named "FILE_1000G.vcf". I would like to rename FILE to match with the user's name. This is my code:


Code:
set -e
echo "Please enter your filename:"
read filename
rename 's/FILE/$filename/' *

The script prompts the user for their name. Say the user inputs John. The desired output woud be John_1000G.vcf


I keep getting the following error:


Global symbol "$filename" requires explicit package name (did you forget to declare "my $filename"?) at (user-supplied code).

NAME
sieveshell - remotely manipulate sieve scripts SYNOPSIS
sieveshell [--user=user] [--authname=authname] [--realm=realm] [--exec=script] server[:port] sieveshell --help DESCRIPTION
sieveshell allows users to manipulate their scripts on a remote server. It works via MANAGESIEVE, a work in progress. The following commands are recognized: list list scripts on server. put <filename> upload script to server. get <name> [<filename>] get script. if no filename display to stdout delete <name> delete script. activate <name> activate script. deactivate deactivate all scripts. OPTIONS
-u user, --user=user The authorization name to request; by default, derived from the authentication credentials. -a authname, --authname=authname The user to use for authentication (defaults to current user). -r realm, --realm=realm The realm to attempt authentication in. -e script, --exec=script Instead of working interactively, run commands from script, and exit when done.
