Populate List Box with list of Strings

Hello,

I would like to give the user the opportunity of choosing a Tag name, which will then show a time series plot of various variables based on that tag name.

I have created this script to create a list of the TAG names, and will then use that selection (onchange) to populate the variables in a graph builder script.

However, this is creating an empty list box. Can anyone identify why?

thanks

Names Default To Here( 1 );
dt = Current Data Table();
ET_LIST = {};
ET_TAG_List = {};

//removes empty column from the column list
For( i = N Col( dt ), i >= 1, i--,
	ET_col = Column( dt, i ) << Get Name();
	If( (Col N Missing( Column( i ) ) / N Row()) != 1 & Contains( ET_col, "ETarg" ),
		Insert Into( ET_LIST, ET_col )
	);
);

Show( ET_LIST );
//takes column list and removes the TAG extension to provide the list of tags
n = N Items( ET_LIST );
For( i = 1, i <= n, i++,
	ETARG = ET_LIST[i] ;
	NFull = Length(ETARG) ; 
	ETTAG = Left(ETARG,(NFull-6)) ;
Insert Into(ET_TAG_List, ETTAG);

);	
	Show(ET_TAG_List);
//want to now take that list and put it into a list box for user to select. will use getselected/onchange to update the charts
New Window( "Example",
	List1 = List Box( ET_TAG_List );
	List1 << Set Items( ET_TAG_List );
);

Re: Populate List Box with list of Strings

The ";" are stopping the processing, change to

New Window( "Example",
	List1 = List Box( ET_TAG_List ),
	List1 << Set Items( ET_TAG_List )
);
