Thanks Sean,

I've tried it a few ways casting as unique identifiers and varchars and none of them seem to be working. I was only playing round with the shorter values and forgot to edit them out of my post :w00t:

I think I may be barking up the wrong tree with this solution anyway but I'll need to split the values out anyway so I'll read the split article shortly.

edit: Thanks, you were all right. Apologies, it's a friday afternoon.

Regards
