Right - I think I've got it sorted. I've added position and count keywords. I spent ages on the indices stuff, then realised I didn't need them as I only wanted to know the elements in one array. Not to worry though - I've always steered clear of the histogram function as it looks horrible, but looking through the routine made me understand it a lot better. So, it wasn't time wasted!

Anyhow, in case anyone wants a quick check the link to the file is below. I'm bound to have done something wrong!
