[support] Setting page meta "description" on View Page

Hi to every body out there.

I've been trying to assign a "meta description" for a page that is generated by using views.

My view page accepts a param. This param is the "initial char" that is used for an alpabetical search of terms (like a dictionary access)

So...the URLs with i'm having problems with looks like this. domain.com/category/a domain.com/category/b .....

In all this pages, including the one generated by a query no parameters ( domain.com/category) there is not "meta description" tag. I've seen that the usual way of dealing with this is through "node words". The point is i'm using it, but it seems it won't display the description tag.

Can anybody give me any tips of how to deal with this?

Thanks in advance
