[Req_Column] can be used to output the names of each of the required fields or columns which were specified for the current database action.

When called with a -Count parameter this tag returns the number of required fields that were specified.

When called with a numeric parameter this tag returns the name of one of the required fields.

Since the -Required command tag can only be used within Classic Lasso actions in HTML forms and URLs, this tag cannot be used within [Inline] ... [/Inline] tags.
