This works thank you very much.  It's 1:am here and I'm very tired so I'm 
going to bed.  But I want to understand your process of determining the 
correct way to get to the field.  I need to be able to do the same thing.  
But when I read the help file I did not understand the notation.  But you 
did!  So if you can take some more time could you explain it.  If this like 
trying to explain OOP then don't of course.  But maybe there is some link or 
text in the help file that will explain the notation? 

Again thanks



PS I think have a little understanding as I re-read the message.  Is aVariant 
one of my controls (or any data type?).
