Problem with LG Better Meta

Hello. I’ve installed LG Better Meta 1.9 into a client’s website and I cannot get my header code to import the meta tags for the weblog I need. The code I’ve added to my header code is:

{exp:lg_better_meta_pl:template entry_id="{segment_3}”}

When I use:

{exp:lg_better_meta_pl:template entry_id="7"}

the tags are imported as I need them to but I need to add the tags dynamically.

Any help would be greatly appreciated.

Thanks,

Ian
