Fotomill,
I believe WWJD is correct, you will need a second table with a sublist of the first. The ttecnigue for creating a sublist has been posted several times and can be seen in the thread:

In your case the formula in the added (and ever popular) hidden column would be based on the criteria that you used to filter your rows. But now that I think about it, your case is easier. Instead of a formula in your hidden column, enter the sequence of integers 1 ... n down the column AFTER you've done your filter. Then complete the formulas for the second table.
And of course, write back if you run into problems -- this is not an easy task if you're just learning Numbers. Welcome and good luck.
