Removing "Selected" Overlay

SO in my game, you click units to select them. Then it makes this little box around them. Here's the code I have.
client/Click(atom/A)
    var/image/I
    var/mob/player/P=usr
    if(istype(A,/mob/units/))
        if(P.selected==A)
            P.selected=null
        else
            I=image('select.dmi',A,"blue")
            P<<I
            P.selected=A


I want to know how to remove the image overlay. I'm probably approaching this the wrong way.

NOTE: I don't want other players to see which units are selected.

del() it.

I actually have that. I didn't put it in the code...because then i figured I'm more asking what's wrong with the code than how to do it.

client/Click(atom/A)
    var/image/I
    var/mob/player/P=usr
    if(istype(A,/mob/units/))
        if(P.selected==A)
            del(I)
            P.selected=null
        else
            I=image('select.dmi',A,"blue")
            P<<I
            P.selected=A

Yet it doesn't work.

The problem is that you're deleting nothing. I isn't going to be the last person you selected because you never told the compiler to do that. The best thing to do is to define a list with the reference to what you clicked.

client
  var/list/selec_list = list()
  Click(atom/A)
    var/image/I
    var/mob/player/P = src.mob
    if(P.selected == A)
      I = selec_list[A]
      del(I)
    else
      I = image('select.dmi', A, "blue")
      P << I
      selec_list[A] = I // use an associative list to hold the reference and image for later deletion
      P.selected = A
