Sub the '+' with an '&'
I name my layouts [MODE] tablename
Mode can be List, Form, Table, Report and other things.
So a simple Go To Form button might be
"[FORM] " & get(layouttablename) or
"[LIST] " & get(layouttablename)
This takes you to the matching form for the current table.
Actually my methods are more complex since I design a layout for iPhone, iPad, IWP and include themes so I can swap at the touch of a button which makes the sale when the prospects eyes light up... :)
