When combo boxes are created automatically through the table
Filter > Control > Combo Box (Drop-Down) Filters on an Output
the Items shown in the control are hardcoded. When users update their data later and more codes are added to the variable used, this will cause issues with the combo box not selecting all respondents so user is then confused as to why it doesn’t work anymore. There isn’t a warning or anything to indicate to the user that the items are out of date because the combo box isn’t linked to the variable used to create it. Recommend bringing this to the user’s attention when they make the combo box OR creating a summary table on a hidden page in the document when running the automation that can be referenced for the item list to ensure the combo box always matches the variable categories. This also comes up when someone relabels a category in a variable used in a combo box, but then the combo box doesn’t work for that category because it’s been hardcoded instead of drawing the items from a table.
