in my RTS Ive created an object. its a little camera tower when you build it you get a verb to switch your view to the camera's for a few seconds..but if I build more than 1 on the map it goes to a black screen then returns to my characters. thats righ, exept for the balck screen.

I want it to bring up a little list that shows which camera.
this is the camera code so far.(btw i use tabs now but for it to fit i have to use 1 spaces)



Camera_Tower
icon = 'Units.dmi'
icon_state = "Camera"
density = 1
var/price = 150
Click()
switch(alert("Do what?","","Sell","Upgrade"))
if("Sell")
for(var/mob/M)
M.Money += price
src.icon += rgb(0,0,40)
sleep(30)
del(src)
sleep(10)
proc
seeit()
for(var/mob/M as mob in world)
if(src.Owner==M.key)
M.client.eye = src.loc

if you need me to post anymore info just tell me.
