Multitouch or is it Drag Object

I have a game where some of it’s functions will be like on the DragMe tutorial. In my game you will take a block and move it to another location. I am working on one of the screens now but I don’t know the proper code to drag or move an object. I read the DragMe code but they are creating their blocks as well as moving them so I don’t know what to keep or delete. Can you tell me how to move my two blocks when a player touches them on the screen? My current code is below. Thanks in advance!
module(…, package.seeall)

function new()
local localGroup = display.newGroup()



local physics = require(“physics”)
physics.start()

local background = display.newImage (“title2.png”)
background.x = 240
–> This sets the background

local instructions = display.newImage (“instructions.png”)
instructions.x = 100
instructions.y = 240
instructions.xScale = .5
instructions.yScale = .5

local highscores = display.newImage (“highscores.png”)
highscores.x = 380
highscores.y = 240
highscores.xScale = .5
highscores.yScale = .5

local floor = display.newImage(“floor.png”)
floor.x = 230
floor.y = 360

physics.addBody( floor, “static”, { friction=0.5, bounce=0.3 } )

local redblock = display.newImage( “redblock.png” )
redblock.x = 180
redblock.y = 50
redblock.rotation = 10
redblock.xScale = .5
redblock.yScale = .5

physics.addBody( redblock, { density=2.0, friction=0.5, bounce=0.5 } )

local redblock = display.newImage( “redblock.png” )
redblock.x = 350
redblock.y = 50
redblock.rotation = 5
redblock.xScale = .5
redblock.yScale = .5

physics.addBody( redblock, { density=2.0, friction=0.5, bounce= 0.5 } )
