Let me speak to it generally, while Jim kind of looks at the specific numbers, because what we're doing and what we're developing, those kinds of things, and it's difficult in one single year to another.... We have, as an agency, increased substantially over the last four years. Both staff and resources have been put into public health activities, both for the support of the system out there, but also here.
So from year to year, moneys will go up and down depending on whether there are specific purchases, specific projects, etc., that are done. Some of them are moved into more effective areas or more appropriate areas. Because once we've done something, then we don't have to do it again. We use that money somewhere else so it moves in column.
