EXCEL MACRO ISSUE - PLEASE HELP
 

I need a button so that when pressed it exports the data from the cell range
sheet 1: A21:S81, it also exports the info from the same range A21:S81 on
sheet 2 to an external excel workbook.

I need it to export all the data onto sheet 1 of the external workbook, and
each time the button is pressed it needs to find the first available row of
the external workbook and copy over, this is so that all data is always saved
on a massive long list.

Thanks
