how to make appear a sprite.sheet right after another sprite.sheet?

Hi guys!!!!!
Again with this tiny problem that I can't solve.
I have a sprite.sheet, after this sprite runs, I want to run other sprite, and so on. How I build the function-timing on they should appear?.

This is the code
(I want to run sprite II right after the sprite I ends.)

--sprite I
local sheet1 = sprite.newSpriteSheet( "image1.jpg", 250, 400 )
local spriteSet1 = sprite.newSpriteSet(sheet1, 1, 8)
sprite.add( spriteSet1, "A", 1, 6, 170, 7 ) 
local instance1 = sprite.newSprite( spriteSet1 )
instance1.x = display.contentWidth / 4 + 16
instance1.y = baseline - 75
instance1.xScale = .5
instance1.yScale = .5
instance1:prepare("A")
instance1:play()
 
-- sprite II
local sheet1 = sprite.newSpriteSheet( "image2.jpg", 250, 400 )
local spriteSet1 = sprite.newSpriteSet(sheet1, 1, 8)
sprite.add( spriteSet1, "B", 2, 6, 2000, 1 ) 
local instance1 = sprite.newSprite( spriteSet1 )
instance1.x = display.contentWidth / 4 + 16
instance1.y = baseline - 75
instance1.xScale = .5
instance1.yScale = .5
instance1:prepare("B")
instance1:play()

That one is easy. Before you call instance1:play()

do this:

instance1:addEventListener( "sprite", nextSprite )

Up above that you will need a function

local function nextSprite(event)
    -- assuming you don't want this to repeat itself
    -- instanc1:removeEventListener("sprite")
    instance1:prepare("B")
    instance1:play()
    return true
end

Hi Rob!, thanks for response.
I must be doing something wrong, because the code doesn't work.
I let you here the code to see what is missing.
Please take a look.

 
--BLOCK I
local sheet1 = sprite.newSpriteSheet( "image1.jpg", 250, 400 )
local spriteSet1 = sprite.newSpriteSet(sheet1, 1, 8)
sprite.add( spriteSet1, "A", 1, 6, 170, 7 )
local instance1 = sprite.newSprite( spriteSet1 )
instance1.x = display.contentWidth / 4 + 16
instance1.y = baseline - 75
instance1.xScale = .5
instance1.yScale = .5
instance1:prepare("A")
instance1:play()
 
local function nextSprite(event)
    -- assuming you don't want this to repeat itself
    -- instanc1:removeEventListener("sprite")
    instance1:prepare("B")
    instance1:play()
    return true
end
 
instance1:addEventListener( "sprite", nextSprite )
 
-- BLOCK II
local sheet2 = sprite.newSpriteSheet( "image2.jpg", 250, 400 )
local spriteSet2 = sprite.newSpriteSet(sheet2, 1, 8)
sprite.add( spriteSet2, "B", 2, 6, 2000, 1 )
local instance2 = sprite.newSprite( spriteSet2 )
instance2.x = display.contentWidth / 4 + 16
instance2.y = baseline - 75
instance2.xScale = .5
instance2.yScale = .5
instance2:prepare("B")
instance2:play()

Try this:

 
--BLOCK I
local sheet1 = sprite.newSpriteSheet( "image1.jpg", 250, 400 )
local spriteSet1 = sprite.newSpriteSet(sheet1, 1, 8)
sprite.add( spriteSet1, "A", 1, 6, 170, 7 )
local instance1 = sprite.newSprite( spriteSet1 )
instance1.x = display.contentWidth / 4 + 16
instance1.y = baseline - 75
instance1.xScale = .5
instance1.yScale = .5
 
-- BLOCK II
local sheet2 = sprite.newSpriteSheet( "image2.jpg", 250, 400 )
local spriteSet2 = sprite.newSpriteSet(sheet2, 1, 8)
sprite.add( spriteSet2, "B", 2, 6, 2000, 1 )
local instance2 = sprite.newSprite( spriteSet2 )
instance2.x = display.contentWidth / 4 + 16
instance2.y = baseline - 75
instance2.xScale = .5
instance2.yScale = .5
 
local function nextSprite(event)
    -- assuming you don't want this to repeat itself
    instanc1:removeEventListener("sprite")
    instance2:prepare("B")
    instance2:play()
    return true
end
 
instance1:addEventListener( "sprite", nextSprite )
instance1:prepare("A")
instance1:play()

I tried, but it doesn't work
we are still missing something.

Now I understand what you did, it looks ok, but the code is not working.

either way, thanks a lot
