Nick,

I'm good thanks. Those templates were written a long time ago so they are probably a little basic.
 * The $group and $prev variables could be defined in the header though you will still need to change prevB in the trailer (0.001 rather than 0.01).
 * Defining $prevB as $groupA is not a bad idea.
 * I think defaults A to zero if it isn't defined. However, it should always be defined in that situation.
 * Testing out dynamic variables was one of the first things I did on the wiki because I put two tables on the same page and they didn't add up properly.
