VLOOKUP from another workbook to first column with same name

Hello guys,

Please can you help me? I have one workbook with macro, dummy2.xlsm. I need if I’ll clik on macro, than put iferror(vlookup) into first blank cell in row 7. Source is in dummy_source.xls, but most difficult part for me is: There are more tables, I need to find same table like in dummy2.xlsm row 5 and put there formula and drag it down.

Values in row 5 are added continuously, so I need fill one column by one click.

dummy_source.xls is editing manually, so I can place name of the table everywhere where is better for macro.

Thank you for helping.
