modeling a head, subsurf problems with lips and chin

image: http://img.photoamp.com/i/JaHpDgl.JPG

how do i fix that thing going on with the lip and chin whe i use subsurf? probably a simple answer, but im pretty new to blender.

and is my head shape ok? is there a guide somewhere to help me shape a head off a face?

thanks!

That gab in the lip and chin is cause by the vertices not meeting.

Try moving the vertices on the lip or chin (where the gap is) closer together and see how it goes.

From what i can see the two halves of your face arent joined, so subsurf is smoothing the corners thus giving you gaps (atleast im preety sure thats what is happening)

oh… they wernt connected.

thanks guys! didnt know that some of my verticies didnt connect! i would never have figured that out.
