movieclip runtime error

I’m getting a runtime error-
[text]movieclip.lua:50: attempt to index field ‘?’
stack traceback:
[c]:?
movieclip.lua:50: in function ‘newAnim’
[/text]
from the following code-

  
 local board3 = movieclip.newAnim( "imagesGame/board.png", "imagesGame/board2.png" )  
 game:insert( board3 )  
 board3.x = 575; board3.y = 200  
 board3.rotation = 1  
 physics.addBody( board3, { density=woodDensity, friction=0.5, bounce=0.2} )  
 board3.myName = "board"   
  
 --Lev 3   
 local rat1 = movieclip.newAnim{ "imagesGame/rat10001.png", "imagesGame/rat30001.png", "imagesGame/rat40001.png" }  
 game:insert( rat1 )  
 rat1.x = 430; rat1.y = 242  
 physics.addBody( rat1, { density=ratDensity, friction=0.5, bounce=0.2,shape=ratShape} )  
 rat1.myName = "rat"   
  

Now if I change the board to below, it works fine. I have a couple of the rat movieclips and it works fine. I tried a couple of other images numbered like the rats too and get the same error.

 local board3 = display.newImage( "imagesGame/board.png", true)  
 game:insert( board3 )  
 board3.x = 575; board3.y = 200  
 board3.rotation = 1  
 physics.addBody( board3, { density=woodDensity, friction=0.5, bounce=0.2} )  
 board3.myName = "board"   

Any ideas? Or does movieclip only work with 1 set of images?

Thanks
