How do I make my while loop constantly check?

local stli = game.Workspace.Lights.Stage.Value
local c = 1
while c < 10 do
    print("run")
    wait(.2)
    if stli == true then
        if c == 1 then
            print("okhand") 
            c = 0   
    elseif stli == false then   
        if c == 1 then  
            print("notokhand")  
            c = 0   
        end 
        end 
    end 
end

There's a folder with the boolean in the workspace. All it will print in the console is one "notokhand" and then no more.

Any help is greatly appreciated, thanks ^^
