Thanks for the help!
I have fixed the original post, no more quotes.
I have fixed the math syntax (no more addition, now using subtraction)
AND, I have attached the whole sketch.
I have not had a chance to try the "delay" fix yet. If I am able to today during lunch I will, otherwise, it will be tonight.
I guess what is messing me up is I am using a sketch for a MAX7219 as a guide and this sketch is just a wee bit different. But with y'alls help I think I will have this fixed.
