more pop-up questions

I don't know why I'm bothering with this stuff - its way beyond me, but its the only way to make my design work.

Anyway, I'm trying to make two different pop-up windows from the same page of different sizes, and I'm having trouble figuring out how to make the right links use the right javascript to create the right pop-up. I assume it has something to do with the name of the pop-up window, but I can't seem to get the syntax right. Any tips?

Thanks in advance! :)
