how do i check a boolvalue in a player?

i'm trying to check a boolean value in the player to see if they have food, and stop the script if they do, or give them food and then set the value to true, but i dont know how to work this out

--this is the value for if you have food or not
local hasIngredient = game.Players:FindFirstChild("hasIngredient")

--this is inside a function
if hasIngredient.Value = true then --this just says expected identifier
	print("you already have one") --just for testing
	end
       else
            if db and player then
		db = false
		foodNumber.Value = foodNumber.Value - 1
		foodLeft.Text = tostring(foodNumber.Value)
	           local inv = player.Backpack 
	           local tool = game.ServerStorage["Tomato"]
	           tool:Clone().Parent = inv
		   hasIngredient.Value = true --i set the has food value to true afterwards
	       wait(2)
		   db = true
		end

in line 7 you must delete end.
