How to make a story game which changes cameras based on a click variable?

so I was working on a Su Tart kind of game and made 2 buttons which went back and fowardth between the story frames, Clicks is the variable and when you clicked the next button it raised the click variable by 1 and the max is 4 and if you clicked previous it would minus the click variable by 1 until 1 so I tried to make if statements to see if the clicks was at a certian number the camera would change positiotns which is a block which is the camera.

here is the script which i believe should be working.

local clicks = 1

script.Parent.MouseButton1Click:Connect(function()
    if clicks== 4 then 
        script.Parent.Parent.prev.Activated = false
        end
    clicks = clicks+1
    print(clicks)
end)

script.Parent.Parent.prev.MouseButton1Click:Connect(function()
    if clicks == 1 then 
        script.Parent.Parent.prev.Activated = false
        end
    clicks = clicks-1
    print(clicks)
end)





--checking 2 pos
while true do
if clicks==1 then

    workspace.Focushere.Position = Vector3.new(-14.077, 4.921, -10.263)
end
wait(0.1)
end

while true  do

if clicks == 2 then
    workspace.Focushere.Position = Vector3.new(-14.077, 4.921, -61.929)
end
wait(0.1)
end

    while true do
if clicks == 3 then
    workspace.Focushere.Position = Vector3.new(-14.077, 4.921, -114.426)
end
wait(0.1)
end

    while true do
if  clicks == 4 then
    workspace.Focushere.Position = Vector3.new(-14.077, 4.921, -164.162)
end
wait(0.1)
end
