Humm. That doesn't seem very widgety to me. :-(

How about creating a text widget, allowing the user
to type as many numbers as they want there, then
taking that line of code, as a string, and using
STRSPLIT to convert the values to numbers:

numbers = Float(StrSplit(textline, /Extract))

Cheers,

David
