forum codes not working?

[Nemesis]

I know nothing of .htaccess stuff so I decided to try that last but I am unsure of what you mean you want me to remove the whole line? Heres what it looks like:

RewriteEngine On


RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^get/([0-9]+).gif$ /adoptables200/siggy.php?id=$1 [L]



I tried some variations but nothing worked :(
