Forum:Changing templates

I have a template that uses a random number to decide what to display. Here I have four of these in a row, and despite the fact that each instance of the changing template is independent of the others, they always show the same image. They should work on their own - so why do they always display the same thing.

Any ideas on how to fix this?  Tardis1963   talk  10:55, October 11, 2012 (UTC)
