HELP!!! BOOLEAN VARIABLES IN LABVIEW

[PRAWG]

Hey guys, I'm having some trouble getting limit switches working in our robot. We are using 3 Limit Switches for different positions on the Lazy Susan. We have planned out the code in notepad as follows,

//ls1 = limit switch 1
//ls2 = limit switch 2
//ls3 = limit switch 3
// 1= go left
//-1 = go right

boolean left = 0
boolean top = 0
boolean right = 0

if (ls1 = 1) then
	left = 1
end if

if (ls2 = 1) then
	top = 1
end if

if (ls3 = 1) then
	right = 1
end if



//button 4
if (left = 1 && top = 1 && right = 0) then
	speed = 1
	if(left = T) then
		top = 0;
		speed = 1until ls1 = 1
end if

if (left = 1 && top = 0 && right = 0) then
	speed = 1
	speed = 1 until ls1 = 1
end if

if (left = 1 && top = 1 && right = 1) then
	speed = 1 until ls1 = 1
end if

if (ls1 = 1 and left = 1) then
	speed = 0
end if

/button 5

if (left = 1 && top = 0 && right = 0) then
	speed = - 1 until ls3 = 1
end if

if (left = 1 && top = 1 && right = 0) then
	speed = - 1 until ls3 = 1
end if

if (left = 1 && top = 1 && right = 1 && ls3 = 1) then
	speed = 0
end if


/button 3

if (left = 1 && top = 0 && right = 0) then
	speed = 1 until ls2 = 1
end if

if (left = 1 && top = 1 && right = 0) then
	speed = -1 until ls3 = 1
end if

if (left = 1 && top = 1 && right = 1) then
	speed = - 1 until ls3 = 1
end if

if(ls2 = 1) then
	speed = 0
end if

We need help initiating a boolean variable(or array), but we cant find it in LabView. help us pl0x.
