Yea, but that's a pretty weak excuse. There's definitely a difference
between a 1 and "1". I venture the implementation of collections themselves
across VB is flawed.

: Adding to Bob's reply, the Key's invalid because it's numeric. You can 
access a ListItem
: using its Key or Index. Since the syntax for doing either is exactly the 
same except for a
: number vs a string, the control won't except an entirely numeric value for 
its Key. If it
: did, there'd be know way for it to "know" whether you wanted ListItem(1) 
as in Index #1 or
: ListItem("1") as in Key = "1". Just tack a letter that can't be confused 
as a number
: (don't use E since it can be used for scientific notation) on one side or 
the other of the
: key and you shouldn't have any problems.
