Hi @afterword ,
I came across this post searching for something similar. If you haven't yet found a solution, try using the <<Set() command where you'd enter the item number for the combo box. In your case, you'd enter 4 because this corresponds to "2009".
Hope this helps,
DS
Try this
Names Default To Here( 1 );
years = {"2006", "2007", "2008", "2009"};
New Window( "test",
modal,
startYear = Combo Box( years,x=years[startyear<<get] ),
startYear << set( 3 )
);
After exiting the window, the variable "x" will contain the selected year.
