I have to say, I don't get how the magic X is supposed to work. Or that is to say, I do, but I don't. Cofused?

When I open the chart, it looks like this


How on EARTH do I apply the magig X to the four seperate charts in the chart?!?!? Like this is looks like I can't cross ie. Glaber with Rare Oak or Pitcher with Scandens because they're in two different places. It has me tearing out hair =S I don't get how to apply the X to the chart when it's divided like this.

Please someone help me before I go even more nuts..
