When I open a certain spreadsheet, I want it to be able to do the following:

On open, the spreadsheet opens another speadsheet on my network but it opens
either hidden to the user or minimised and read only so that no changes can
be made.

Sounds a bit strange but its because the second spreadsheet contains loads
of lists which the first spreadsheet references (dynamic name ranges for
validation lists). but I dont want the second spreadsheet to be altered.

Thanks in advance for your help.

Kind regards,
