Creating a slow zoom?

Hi,

Thanks to everyone who has helped on previous questions.  This is a great user group.

I put zoom in at 11 seconds and want it to slowly zoom in on a part of the page...and have it take 2 or 3 seconds to get there...then I want to do the reverse and take 2 or thre seconds to zoom back.  Ive got the zoom action in the timeline...that spans the time I want it to take...but it always just zooms in right away and takes a half second or less to get there.  The timing feature doesn't seem to be any help as no matter what i do...it zooms in...literally! (and I want it to go slower).

In camtasia, you can adjust how long a zoom takes and I bet there's a way to do it in Articulate. No?
