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, instead of putting empty into the line that has the name you
want to delete simply use the delete command
delete line x of field "foo"
I assume you are using the find command to find the name to remove. If
so, then you can use the value returned by the FoundLine() function.
Specifically:
find x in field "foo"
if the result is not "not found" then
get the foundline
delete line (word 2 of it) of field "foo"
end if
....
As to scrolling fields check out the Power Tools stack and see how it
is done there. That shows one way to do it effectively.
Hope that helps...
