MovieClip Duplication then getting into it

Evening all

I have created a flash movie and I am now a bit stuck.

I am attempting to duplicate a movie 5 times or so, move it from left to right, however I would like each image to be a random image.

I have created the code and duplicated it however for some strange reason I cant get the image to move away from the first one in the images mc.

SO BASICALLY I WANT A RANDOM IMAGE IN EACH MOVIECLIP

I have attatched the file and any help sorting out this bug would really be very much appreciated.

I think its the part between the //CAMERON tags but I honestly just cant work it out.

Thanking everyone in advance

Cameron
