Vista - How do I properly use IsSharedSizeScope ?

Hi,

I have the following code. Its goal in life is to show a variable number
of products with a header on the top and a total / subtotal section at
the bottom.

I can't get the line items to line up with the rest, any ideas why?

Phil

PS Also, the grid lines are dotted, how can I set them to be only black?

PS2 here is the relevant code
