I seem to have got around this error somehow after ignoring it for a
while & tidying up some code. I would still be interested to know how &
why this can occur. Surely the ItemIndex property is always an integer!
On another topic, when creating another instance of an object, does the
data in the new instance contain the data that was contained in the
previous instance. This is what appears to be happening but I would
prefer the new object's elements to be blank/zero. Do I have to
initialise the all the elements by name?
Thanks,
Ross.
