Compare two md5sum

Hello,

First of all I want to apologize because i'm not a admin or coder and maybe all my efforts to write only this small script in my life would need one week full time reading man pages and forums but...
I don't have the money to offer me to get this time and the script I want to do seems very simple, what I want to say is my errors in the script are newbie ones...

I want to do this :

Code:
#!/bin/bash

$1=52f8422918c5347166dbb40c76f95e9c

checksum=`curl --silent httptheurliwanttocheck | md5sum`

$2=checksum

if [ "$1" = "$2" ]
then
    echo "nothing"
else
    echo "change"
fi

but it doesnt work.
after this works I want to this script to really do nothing if nothing changes and to send me an email if there is a changement. It takes me super long time to understand all these stuff and i'm now thinking about forgetting this and going every day to see if the page changed... This post is my last try.

If its insult to the unix community to ask this I'm sorry.

NAME
script -- make typescript of terminal session SYNOPSIS
script [-a] [-k] [-q] [-t time] [file [command ...]] DESCRIPTION
The script utility makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1). If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript. If the argument command ... is given, script will run the specified command with an optional argument vector instead of an interactive shell. Options: -a Append the output to file or typescript, retaining the prior contents. -k Log keys sent to program as well as output. -q Run in quiet mode, omit the start and stop status messages. -t time Specify time interval between flushing script output file. A value of 0 causes script to flush for every character I/O event. The default interval is 30 seconds. The script ends when the forked shell (or command) exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not set) for the C-shell, csh(1)). Certain interactive commands, such as vi(1), create garbage in the typescript file. The script utility works best with commands that do not manipulate the screen. The results are meant to emulate a hardcopy terminal, not an addressable one. ENVIRONMENT
The following environment variable is utilized by script: SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most shells set this variable automatically). SEE ALSO
csh(1) (for the history mechanism). HISTORY
The script command appeared in 3.0BSD. BUGS
The script utility places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects. It is not possible to specify a command without also naming the script file because of argument parsing compatibility issues. When running in -k mode, echo cancelling is far from ideal. The slave terminal mode is checked for ECHO mode to check when to avoid manual echo logging. This does not work when in a raw mode where the program being run is doing manual echo. BSD
