I have Maya 2009. I created a polygon cylinder and am trying to squeeze the center vertices in. I turn on component mode and i can see all the vertices, but it won't let me select the ones i want. It highlights the whole cylinder and won't let me manipulate individual vertices.

i've tried everything. i've tried making a new cylinder. i've selected, deselected, right clicked. Every i do it selects the whole thing and won't let me select individual vertices.

Is there a setting i need to turn on or off? My friend also has Maya 2009 and he can edit polygon vertices no problem, right in front of me. I can't! What's going on?
