Ah, the classic toggle coil conundrum.  This is the first thing I teach in my PLC class and is a lot harder than it looks until you've seen it done.  It takes a while to get a real feel for the way a PLC solves it's program and the power of bits.

 

I'd highly recommend taking an hour or so with the Help file and going through each function in the first couple of menus - Boolean, Compare, Math, etc.  It really helps to know what tools you have available and how they work.
