I want to program a macro button to open another Workbook from within my
presently opened Workbook.
The Workbook that I want to call is named 'Stock Plan Blank' and is stored on my PC on D:\My Documents\Excel
I also want it to copy one spreadsheet named 'Stock Plan' from the Workbook i'm working in to Sheet1 of the workbook I want to open.

How do I call it up and copy??

Easy for those that know how.
