Many thanks, using references solved the problem. I note that using: 
 %tmpF->{ID}

[download]
and 
 $tmpD{ID}

[download]
seems to make no difference, both work. What are your reasons for suggesting the bottom way over the top way? I am not trying to say you are wrong! far from it, I just want to know why you would do it that way :) TienLung
