Hiya,

I have a field that holds a list of people to which names can be added,
and deleted.  When changes are made, I resort the field alphabetically, but
this does not work so well when I have deleted a name from the list.

To delete a name, I search for the name, determine what line it is on and then
put EMPTY into that line.  Upon resorting the name list, that empty line
(which I thought ws transparent to HC 2.0) then gets shuffled to the top
when I sort ascending.  Hpow do I get rid of this empty line? Any suggestions?

My second problem deals with getting two separate scrolling fields to scroll
in tandem with each other (ie when I scroll one the other scrolls to the 
same position).  I have been able to do this rather crudely using the Scroll
parameter but this brings up the problem.  These fields are going to have
data input by the user.  I have found that once the last visible line in
the field is reached and data is input into the first field, the second fails
to scroll (obviously this is caused by the fact that the second field has no
data where the first is telling it to scroll).  Any ideas?

Thanx a bunch!

Scott
