would it be possible to place two intersect in a single line syntax? i mean i'm trying to make a puzzle puzzle game wherein

a is connected to b and c by a line and c is connected to d
-initial is you may click a or b but can only click c if a or b is clicked. and d may only be clicked if c is clicked.

now i already typed this script

case spritenum of
-- 2:
-- ---on click button lights up or closes
-- if sprite(spriteNum).member = member ("c1") then
-- sprite(spriteNum).member=member("o1")
-- else
-- if sprite(spriteNum).member= member("o1") then
-- sprite(spriteNum).member=member("c1")
-- end if
--
-- end if
-- 3:
-- ---on click button lights up or closes
-- if sprite(spriteNum).member = member ("c1") then
-- sprite(spriteNum).member=member("o1")
-- else
-- if sprite(spriteNum).member= member("o1") then
-- sprite(spriteNum).member=member("c1")
-- end if
-- end if
-- 4:
-- ---on click button lights up or closes
-- if sprite(spriteNum).member = member ("c1") then
-- sprite(spriteNum).member=member("o1")
-- else
-- if sprite(spriteNum).member= member("o1") then
-- sprite(spriteNum).member=member("c1")
-- end if
-- end if
-- 5:
-- ---on click button lights up or closes
-- -- if sprite(spriteNum).member = member ("c1") then
-- -- sprite(spriteNum).member=member("o1")
-- -- end if
-- --- if the sprite before is off
-- if sprite(4).member = member("c1")then
-- sprite(spriteNum).member = ("c1")
-- else
--
-- set the member of sprite (5) to "o1"
--
-- end if

but is it possible for it to call on 'check if the spritenum is intersected to ("line") which intersects with a "cl" for the member to be set to 'ol''?
