Thank you it works if you are in the same workbook to start from a separate wb not I can run the macro with

Application.Run "'C:\Users\Q36804\AppData\Roaming\Microsoft\Excel\XLSTART\PERSONAL.xlsb'!get_boards"

or with a Parameter

Application.Run "'C:\Users\Q36804\AppData\Roaming\Microsoft\Excel\XLSTART\PERSONAL.xlsb'!get_boards", lr
