No, you can't do that - as Forms already told you, this is an error.
Something's wrong with either data model or its implementation. If the requirement says that there should be two form items, then the table should contain two columns (instead of one). Or, if it *must* be a single column, then you'd also use a single form item.
However, if you insist, then create two non-database items that are visible on the form. A database item doesn't have to be visible; populate it in one of form triggers (either after those two non-database items are populated - that might be a WHEN-VALIDATE-ITEM on the second item), or before inserting records into the database (in that case, you'd use PRE-INSERT trigger).
