Juamei - thank you so much for taking the time to investigate that. That's what I love about this site - the help, advice and assistance that everyone is willing to give. Without wanting to sound over the top, the fact that it's been fixed means a lot to me, it took me ages to put together and I was somewhat forlorn when I thought it had been lost.

TMA Ed's - thanks for taking the time, in what it undoubtedly a very busy schedule, to put it right again, it's much appreciated.

Cheers all

A very happy Jacksprat. :op
