You cannot change the names of form objects during runtime.
When you repeat an existing row, all child elements (cells) will have the same name as in the other instances of the row.
Table1.Row[0].Cell1, Table1.Row[0].Cell2, Table1.Row[0].Cell3 etc.
Table1.Row[1].Cell1, Table1.Row[1].Cell2, Table1.Row[1].Cell3 etc.
Table1.Row[2].Cell1, Table1.Row[2].Cell2, Table1.Row[2].Cell3 etc.
Table1.Row[3].Cell1, Table1.Row[3].Cell2, Table1.Row[3].Cell3 etc.
If you make those cells binding global all cells with the same name will be global too and have the same value.
