Weird glitch, or am I doing everything wrong? (shell.run)

local function main()

startY = 3,
endX = 4,
endY = 5,
run = function() print("Hello!") end
}
}

local items = {
"One",
"Two",
"Three",
"Four",
"Five",
}

local function draw()

term.setBackgroundColor(colors.white)
term.clear()

Draw.barDraw(buttonsT,currentMenu)
Dropdown.dropdown(2,10,items,"Three",buttonsT)

end

local function buttons()
Buttons.initializeButtons(buttonsT)
end

local function loops()

while true do
os.pullEvent()
if doRedraw == true then
draw()
doRedraw = false
end
end

end

draw()

Menu.initalize(buttonsT, currentMenu, doRedraw, shell.getRunningProgram())

parallel.waitForAll(buttons,loops)

end

print("Error: "..err)
print("Please report this error on the Github repository")
print("Press key to reboot...")
os.pullEvent("key")
os.reboot()
end
