Quirk with my clocks

I just wanted to give a big thank you to everyone who attempted to help me with my project...I've finally gotten to a point where I could turn it in right now if I had to which is a pretty awesome feeling since I still have a week and a half to work on it.

The only functionality that I have not yet been able to meet that I had set out for myself is retaining a high score for my game, and then displaying that score on the LCD screen.

My thought is that I could use the lpm_compare megafunction to determine if the new number is higher than the old number and then output the higher of the 2 but it doesn't seem to work, the lpm_compare works just not when I make my circuit dynamic and have changing values.

Does anybody have any ideas or things that I should check out that might point me in the right direction? We haven't covered any sort of rom or ram in our class...I tried figuring out the different memory megafunctions but I'm struggling.

I appreciate any help...
