XP X AND Y COORDINATES

Why is it that when I make it so if one sprite is equal to another's X and Y it destroys it, it only works every other time? Like when I load up the game I have 7 sprites done, but only four show up and nothing, coding wise, is wrong. XP is really pissing me off right now. I also hate how everything is reworded cause I'm used to 2003 not XP.

Nope...
