Re: The set does not exist
There is the answer: "the data source is arrays". The highlight set only applies to selection (table) based list boxes. To get the highlighted rows of an array listbox, you use the True/False value of the boolean array representing the listbox. See the "Managing Selection" section on the page below. https://doc.4d.com/4Dv17/4D/17.2/Managing-List-Box-Objects.300-4386875.en.html John DeSoi, Ph.D. > On Jul 7, 2019, at 4:42 PM, Carl Aage Wangel via 4D_Tech > <4d_tech@lists.4d.com> wrote: > > I am using the right listbox name (listbox object name) and the data source > is arrays.

Re: The set does not exist
The highlight set for a listbox is set in the listbox properties. If this is empty, then there is no highlight set. If the listbox set name you are trying to use does not match the listbox set name property then you are not going to get the anwer(s) you expect. If you want I have an old demo/source code for list boxes which I'll share, send me an email Chip > Replying to myself here(!) but I should also have mentioned a third > thing to check: > > * have you used the correct name in the $ListBoxName variable? > * what does $tableNum contain?
