Hacktendo timestamps

I am getting so frustrated with these stupid timestamps. I mess around with the code for hours, FINALLY get it to work, and the next day when i get on the same exact code isn't working. So maybe this isn't a scripting error on my part, maybe the timestamps just aren't working, I don't know.

In my script I have it create a timestamp when you press down the button, which corresponds to which direction you're trying to go (up,down,left,right). When this occurs, I use setLocal to tell it which direction it's going and to tell it that it needs to move. Basically, now, whenever I manage to get the sprite to move at all, it moves only once when I hold down a button, unless I tell it to go when the timestamp is equal to 0, which makes the animation go way too fast. Can any devs help out here?
