[MOD] Facebook Like Button on Product Page

Works for me on V1.5.3.1, unfortunately I am a pure hands novice, and do not know how to r
write VQmod's - sorry

Almost got this to work meta is coming nicely to header when looking at the source BUT getting this error

Notice: Undefined variable: result in /public_html/vqmod/vqcache/vq2-catalog_controller_product_product.php on line 410

Any idea?
