I've had a chance to load MS Office on my computer and have looked over Walter. By my count, he's spent only 42 of 44 skill points. I didn't see where melee and ranged attack with the dagger is differentiated, but it being your character sheet as long as you remember that Walter is better at throwing daggers than stabbing with them, it seems okay to me. After that, everything else looked correct. I matched his strength to his encumbrance limits but didn't tabulate the weight or cost of his gear. The only thing I didn't see that I'd want to know is what spells he's got. Unless it's in there but I somehow missed that section?
And may I just say, that is one powerful Excel macro you have there. Did you do that yourself or did you download it?
