Do "work" when you select an item in the Data Filter

[#1]

I am having trouble figuring out how to do "work" when you select a item in the data filter. When i select a condition I would like the script to go to my Limits Table and then populate an expression that i use for a Graphics Script. This will change based on the "where" statement from the data filter. I don't know how to get the script to trigger this action or how do you delete it if i were to change to a different data filter selection. I apologize in advance as i don't have the entire script or a sample data table. If more information is needed I will try my best to get some.

Thanks

// Step 1: Go to the textbox with "Where" statement

Try( test = Report( gb1_S.2 )[Text Box( 5 )] << Get Text );
graph = dt_lim << Get Rows Where( Contains( test, :SPEC_COL_NAMES ) );

// Step 2: If a condition exists, populate the following

f1 = Column( dt_lim, "StartF" )[graph][1]; // x1 for a Marker and starting point for the line
f2 = Column( dt_lim, "StartF" )[graph][2]; // x2 for a Marker and starting point for the line
s1 = (Column( dt_lim, "LSL" )[graph])[1]; // y1 (LSL) for the Line
s2 = (Column( dt_lim, "USL" )[graph])[1]; // y2 (USL) for the Line

color = "Red";

test = Expr(
	
	graph_expr = Eval Insert(
		"\[Graph_Script = Expr(
			Marker Size( 6 );
			Marker( Marker State( 20 ), Color State( "^color^" ), {^f1^, ^s1^}, {^f2^, ^s2^} );
			Pen Color( "^color^" );
			Line( {^f1^, ^s1^}, {^f2^, ^s2^} );	
		)]\"	
	);

	Eval( Parse( graph_expr ) );
	
);


// Step 3: Execute the Graphics script

Report( gb1_S.2 )[Framebox( 1 )] << Add Graphics Script( Graph_Script );

Check out Make Filter Change Handler from Scripting Index on how to trigger action when filter selection is changed.

Example from scripting index:

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Cities.jmp");
dist = Distribution(Automatic Recalc(1), Continuous Distribution(Column(:POP)));
filter = dist << Local Data Filter(Add Filter(columns(:Region)));
f = Function({a}, Print(a));
rs = filter << Make Filter Change Handler(f);
