Can anyone help with this locking script?

Also anyway to clean it up

glockdown = script.Parent.Parent.Parent.GlobalLockdown
dlockdown = script.Parent.Parent.Parent.DoorLockdown

script.Parent.ClickDetector.MouseClick:connect(function (pwc)
	print ("Check Click One")
        if dlockdown.Value == false and
	    pwc.Name == workspace.ShipCrew.Captain.Value or 
	    pwc.Name == workspace.ShipCrew.FirstOfficer.Value or 
	    pwc.Name == workspace.ShipCrew.SecondOfficer.Value or 
	    pwc.Name == workspace.ShipCrew.EngineeringChief.Value or 
	    pwc.Name == workspace.ShipCrew.EngineeringJuniorOne.Value or 
	    pwc.Name == workspace.ShipCrew.EngineeringJuniorTwo.Value or 
	    pwc.Name == workspace.ShipCrew.TacticalChief.Value or 
	    pwc.Name == workspace.ShipCrew.TacticalJuniorOne.Value or
	    pwc.Name == workspace.ShipCrew.TacticalJuniorTwo.Value or
	    pwc.Name == workspace.ShipCrew.MedicalChief.Value or
		pwc.Name == workspace.ShipCrew.MedicalJuniorOne.Value or
		pwc.Name == workspace.ShipCrew.MedicalJuniorTwo.Value or 
	    pwc.Name == workspace.ShipCrew.ScienceChief.Value or
		pwc.Name == workspace.ShipCrew.ScienceJuniorOne.Value or
		pwc.Name == workspace.ShipCrew.ScienceJuniorTwo.Value or
	    pwc.Name == workspace.ShipCrew.OperationsChief.Value or
		pwc.Name == workspace.ShipCrew.OperationsJuniorOne.Value or
		pwc.Name == workspace.ShipCrew.OperationsJuniorTwo.Value 
	    then 
	    print("Check One")
         dlockdown.Value = true
         script.Parent.Lock:Play()
end
end)

    script.Parent.ClickDetector.MouseClick:connect(function (pwc)
	print ("Check Click Two")
        if dlockdown.Value == true and
	    pwc.Name == workspace.ShipCrew.Captain.Value or 
	    pwc.Name == workspace.ShipCrew.FirstOfficer.Value or 
	    pwc.Name == workspace.ShipCrew.SecondOfficer.Value or 
	    pwc.Name == workspace.ShipCrew.EngineeringChief.Value or 
	    pwc.Name == workspace.ShipCrew.EngineeringJuniorOne.Value or 
	    pwc.Name == workspace.ShipCrew.EngineeringJuniorTwo.Value or 
	    pwc.Name == workspace.ShipCrew.TacticalChief.Value or 
	    pwc.Name == workspace.ShipCrew.TacticalJuniorOne.Value or
	    pwc.Name == workspace.ShipCrew.TacticalJuniorTwo.Value or
	    pwc.Name == workspace.ShipCrew.MedicalChief.Value or
		pwc.Name == workspace.ShipCrew.MedicalJuniorOne.Value or
		pwc.Name == workspace.ShipCrew.MedicalJuniorTwo.Value or 
	    pwc.Name == workspace.ShipCrew.ScienceChief.Value or
		pwc.Name == workspace.ShipCrew.ScienceJuniorOne.Value or
		pwc.Name == workspace.ShipCrew.ScienceJuniorTwo.Value or
	    pwc.Name == workspace.ShipCrew.OperationsChief.Value or
		pwc.Name == workspace.ShipCrew.OperationsJuniorOne.Value or
		pwc.Name == workspace.ShipCrew.OperationsJuniorTwo.Value  
	     then 
	print("Check Two")
	     dlockdown.Value = false
	     glockdown.Value = false
		 script.Parent.Unlock:Play()
     end
end)

Since we've already discussed the problems on Skype, here's the fixed script:

glockdown = script.Parent.Parent.Parent.GlobalLockdown
dlockdown = script.Parent.Parent.Parent.DoorLockdown

--List the ranks that can use the door here, follow the format shown.
local ranks = {
"Captain",
"FirstOfficer",
"SecondOfficer",
"EngineeringChief",
"EngineeringJuniorOne",
"EngineeringJuniorTwo",
"TacticalChief",
"TacticalJuniorOne",
"TacticalJuniorTwo",
"MedicalChief",
"MedicalJuniorOne",
"MedicalJuniorTwo",
"ScienceChief"
"ScienceJuniorOne",
"ScienceJuniorTwo",
"OperationsChief",
"OperationsJuniorOne",
"OperationsJuniorTwo"
}
--End rank list

script.Parent.ClickDetector.MouseClick:connect(function (pwc)
	print (pwc.Name.." clicked")
	if dlockdown.Value == false then
		print("Door is not locked.")
		for i,v in ipairs(ranks) do
			if pwc.Name == workspace.ShipCrew[v].Value then
				print(v.Value.." "..pwc.Name.." passed check. Locking door.")
				dlockdown.Value = true
				script.Parent.Lock:Play()
			else
				print(pwc.Name.." did not pass check.")
			end
		end
	elseif dlockdown.Value == true then
		print("Door is locked.")
		for i,v in ipairs(ranks) do
			if pwc.Name == workspace.ShipCrew[v].Value then
				print(v.Value.." "..pwc.Name.." passed check. Unlocking door.")
				dlockdown.Value = false
				script.Parent.Lock:Play()
			end
		end
	end
end)

The reason it was throwing the "Unknown Global" was because I forgot to make the ranks strings, so ROBLOX was looking for the variables "Captain", "FirstOfficer", etc. That's fixed now.
