Multiple selections from option list

I would like to be able to allow multiple selections from an option list. For example: the list of options is the months of the year. The selection would be June and July. How can I save both options in a table?

Multiple selection is not possible with the option type, you need to realize this lookup and selection via a table with its respective form where you can either mark (Ctrl+F1) or highlight (Ctrl+mouse click)the records you want to process or select - finding out which records are marked or highlighted has to be done via coding… Saludos Nils
