Trying to make an exit inventory button on coronasdk

Question

I am currently working on a game what requires an inventory system. I cannot work out how to make an exit button for a display object I created.

Here is my code :

local Choose_slot = display.newImage("Images/choose_slot.png")
 Choose_slot.x = centerX + 96
 Choose_slot.y = 45

function choose_slot:tap ( event )
  Inventory_Screen = display.newRect( centerX, centerY, 1500, 1500 )
  Inventory_Screen:setFillColor( 0.3, 0.3, 0.3 )
end

local Exit_Button = display.newImageRect( "Images/Exit_Image.png", 32, 32)
Exit_Button.x = centerX + 255
Exit_Button.y = centerY - 135

function Exit_Inventory:tap ( event )
    Inventory_Screen:remove()
    Exit_Button:remove()
end

Exit_Inventory:addEventListener( "tap", Exit_Button)

Choose_slot:addEventListener( "tap", choose_slot)

Just for your Information, "Choose_slot" is an image that brings up the inventory. I would like to make it so when the "Inventory_Screen" comes up the "Exit_Inventory" button pops up and when you tap it, it removes the "Inventory_Screen" and the "Exit_Button" from the screen and goes back to screen you were on before you clicked inventory!

The picture is what left after I changed your code to this:

function Choose_slot:tap ( event )  

        Inventory_Screen = display.newRect( centerX, centerY, 1500, 1500 )
        Inventory_Screen:setFillColor( 0.3, 0.3, 0.3 )

        local function handleExitBEvent( event )   -- ERROR IS BELOW! 

    if ( "ended" == event.phase ) then
        print( "Button was pressed and released" )
        print( "Removing Inventory!" )
        Choose_slot:removeSelf() -- This is not removing -- 
        ExitB:removeSelf()
        Inventory_Screen:removeSelf()
        Inventory_Slot1:removeSelf()
    end
end
