Ha! Didn't think to look there. Thanks a lot, Randomizer. Now I can stop tearing out my hair.

I've taken a screen shot and tried countless number combinations with the tactical grid on. I would post the image here except I have no idea how to do so. The reveal map spell, level 5, shows nothing. Anyone have any further advice as to how to determine the darned code from what is displayed?
