In v18 project mode, field objects on the form have been replaced with the input object. To associate a table-field to the input object, the 4D standard field expression can be hard-coded in the 'variable or expressions' property.



Another way to associate a table-field to an input object is to perform a Shift+Right Click on the input object. The list of all visible tables and fields will appear as a popup dropdown list, ready to be selected.
