AutoIT (Help Pl0x)

Hi there! =) I was download AutoIT for 3 days ago or something like that, i've been reading tutorials etc!

But now i want a function to work.

I want it to be like this:

I save codinates example and the color:

$color = PixelSearch( 150, 150, 250, 250, 0xFFFFFF, 2, 2 )

This is also the variable then.
AND Now what i want to do is that i want a Loop that is looking for this, and when this color is detected in the cordinate box then a msgbox will popup!

How do i program this!? My brain isn't big enough to understand how :S

I need also make a loop or something that must check this all time until the msgbox comes up.

grrrr plz someone
