XML Load & Hyperlink

I am loading a set of images into masked movie clips via an XML file, and then attemting to hyperlink the Movieclip with a URL obtained from the XML.

The problem I am having is that the 1st, 3rd, 5th and 7th clips are not behaving as if they have a hyperlink attached to them the others are fine.

I'm sure I'm missing something really obvious here, but for the life of me I can't see it... someone put me out of my misey please, code is attached, let me know if you want all the files and I will email them over.

Cheers
