ActionScript 3.0 :: Hittest Object Within An Object Array?

I have a function that checks if 2 objects are touching OB1 and OB2, if they do touch it runs the rest of the collision code where OB1 is the character and OB2 is a tile that the player cannot pass through.

I came across an issue where i wanted sprites to be separate from the hitboxes but my collision code works by checking the height and width of an object (you guys know the drill).

So i have a Tile class with 2 parts to it, a bitmap and a movieClip.

So i have this setup(pseudocode):

Code:
loop
{
function collision (ob1 , ob2[loop].movieclip)
}

This should work right? But it ONLY works for the first object in the loop!
