Detecting object in an area one by one

[elautor]

hello

Im having a little bit of an issue detecting an image over certan area.

To be more precise, im trying to make a similar to ddr (dance dance revolution) game with the key pad. So far id had no problem since its a simple thing to do; but now im stuck at something.

until now i was able to set that when the player presses (x)(or any other button taht corresponds to the image) it stores the certain value to a variable that i will later pas to a "helt bar".

Ihave also manage to set diferent "points" (healt) depending on the area the image was when the player pressed the button (the mmore exact the timing the more points and healt.

But my problem consist when 2 images enter the same valued area.
If the player preses the button both images dissapear .
This migth seem simple but beleieve me ive tried everithing i could...flags...variables...ifs....and it stills erases the images taht are in the same area...i woould apreciate any help and please excuse my english, it is not my native language.

thanx in advance

I made an example to help.
example
It uses 3 objects instead of 1 bullseye. It ranks you based on how close to the center you get.
Outer ring=1
In between outer and center ring=2
Center ring=3
In between center ring and inner =4
Inner=5

Hope this helps.
