I am trying to update a file that contains the md5 checksum for a file if the value in the file is different from the new md5checksum but it is not updating. Here is the code, any suggestions are greatly appreciated. 

         if ( &download( $url, $save_file ) ) {

            # Successfully downloaded, now compair previous md5 value 
            # and if different move to the transfer folder

            my ( $guidId, $ext ) = split ( '.zip', $guid );
            my $md5File = "${hifld_md5_folder}/${guidId}.md5";

            open ( MD5, '+>>', $md5File )
               || &loggingError("Couldn't open md5 file ($md5File) for
+ reading : $!");

            $md5row = <MD5>;
            close( MD5 );

            my $md5chksum = &calcMD5( $save_file );

print "md5row    = ${md5row}\n";
print "md5chksum = ${md5chksum}\n\n";  
            
            # check to see if the file has changed since the last down
+load
            # if not then delete the downloaded file otherwise
            # update the md5 file and rename the downloaded file for m
+oving
            if ( $md5row = $md5chksum ) {
               my $cmd = "rm $save_file";
#               `$cmd`;
            } else {
               # Update the md5 file
               open ( MD5OUT, '>', $md5File )
                  || &loggingError("Couldn't open md5 file ($md5File) 
+for writing : $!");

               print MD5OUT "${md5chksum}";
               close( MD5OUT );
