Update access list script

Hello! I need to update access list and i decided to do it via script. I found it here https://wiki.mikrotik.com/wiki/Using_Fetch_and_Scripting_to_add_IP_Address_Lists. After main script, i entered my 3 lines of code:

:log info "Update!!";
/file remove [find where name=kg-nets.txt];
:log info "File deleted";

When i script, it update address-list, but the last 3 lines of code, which i entered, does not execute.
So, why it does not execute lines:

:log info "Update!!";
/file remove [find where name=kg-nets.txt];
:log info "File deleted";

This is full script:

{
/tool fetch url="http://ip.elcat.kg/kg-nets.txt" mode=ftp
:if ( [/file get [/file find name=kg-nets.txt] size] > 0 ) do={
   /ip firewall address-list remove [/ip firewall address-list find list=KG-ZONE];
   
   :global content [/file get [/file find name=kg-nets.txt] contents] ;
   :global contentLen [ :len $content ] ;
   
   :global lineEnd nil;
   :global line "";
   :global lastEnd nil;
   
   :do {
         :set lineEnd [:find $content "\n" $lastEnd ] ;
         :set line [:pick $content $lastEnd $lineEnd] ;
         :set lastEnd ( $lineEnd + 1 ) ;
        :local entry [:pick $line 0 ($lineEnd -1) ]
        :if ( [:len $entry ] > 0 ) do={
           /ip firewall address-list add list=KG-ZONE address=$entry;
        }
   }  while ($lineEnd < $contentLen);
}
:log info "Update!!";
/file remove [find where name=kg-nets.txt];
:log info "File deleted"; 
}

Help me, please
