Do you want the form to do anything, or just to flash up, a splash screen?
If the latter, see http://www.xldynamic.com/source/xld.xlFAQ0007.html

How do you want the selection to be invoiced.

I have a workbook with 30-40 different sheets, i have a command button on
each sheet that start a macro called Sub Producedwatersystem().

Is it possible that a form can appear at the same time as the workbook is
opened?
(a opening page).

Is it possible that the user can choose what sheet to be active and start
the macro from that form?
