Call function in checkbox

[#1]

Hi,

I am building a simple interface for the user and have a window to set some options using check boxes. 

I am currently able to make the first call function and the script filters the string "SE" from the columns and generates outliers. However, if I check 2nd and 3rd checkbox it does not call the function

 I tried the following script:

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Water Treatment.jmp");

check_list = {"SS", "SE", "PH"};

todo_list  = {};


nw = new window("Checkboxes", << modal(),

     my_cb = checkbox(check_list),

     panelbox("Actions",

           hlistbox(

                button box("OK",

                     keep_going = 1;

                     todo_list = my_cb << get selected;

                ),

                button box("Cancel", keep_going = 0)

           ),

     ),

);

nt = nitems(todo_list);
colList = dt << Get Column Names("String");
filteredCols = {};


if (keep_going & nt > 0,

     for (i = 1, i <= nt, i++,

           if (todo_list[i] == "SS",

//              Call function for One step

For(i = 1, i <= N Items(colList), i++,
	If(Contains(colList[i], "SS"), Insert Into(filteredCols, colList[i]))
);
obj = dt <<
Explore Outliers(
	Y((Eval(filteredCols) )));

obj << Quantile Range Outliers;
obj << Select Rows(All);
                ,

                todo_list[i] == "SE",

//              Call function for Two step

               For(i = 1, i <= N Items(colList), i++,
	If(Contains(colList[i], "SE"), Insert Into(filteredCols, colList[i]))
);
obj = dt <<
Explore Outliers(
	Y((Eval(filteredCols) )));

obj << Quantile Range Outliers;
obj << Select Rows(All);
				,
				todo_list[i] == "PH",

//              Call function for Three step

               For(i = 1, i <= N Items(colList), i++,
	If(Contains(colList[i], "PH"), Insert Into(filteredCols, colList[i]))
);
obj = dt <<
Explore Outliers(
	Y((Eval(filteredCols) )));

obj << Quantile Range Outliers;
obj << Select Rows(All);


           );

     );

);

Looking for some feedback

Thanks,

Jack

You are using the index "i" for all of your For() loops.  That means that the value of "i" is getting changed all over the place.  You need to use different variables for your For() loops when there is a loop within a loop.
