Challenges constructing a proper loop

[#1]

Hi, 

Im new to coding and having challenges constructing a functioning script

dt = current data table();
//declaring and initializing variables//
lt_min = 1;
lt_max = 50;
RSquare_th = 0.9999;
count = 0;
//loop
while (count < 0.99999, 
//calculate x for each y value
dt << New Column ("x", Numeric, formula(:y/ (:y + :avg_num)));
//plot bivariate
biv = dt << Bivariate( 
	Y( :x ),
	 X( :average_temp),
	 Fit Line( {Line Color( {212, 73, 88} )} ));
Bivariate_report = biv << report;
pt = Bivariate_report [Table Box(1)];
pt << Make Combined Data Table();
pt = Bivariate_report [Table Box(3)];
pt << Make Combined Data Table();
);
//get rsquare
rsquare << send (Bivariate Fit);
rsquare  << send(Get Gen RSquare Test);
//check Rsq
if (rsquare < RSquare_th,
	//increment light by 1
	lt_min = lt_min +1,
	count = count +1,
	//update data table
	dt << New Column("light", Numeric, formula(lt_min)),
	//exit loop if RSQ >= threshold
	print("Search Completed. RSQ >= threshold"),
);

Use ctrl-M in the editor to format the jsl:

dt = Current Data Table();
//declaring and initializing variables//
lt_min = 1;
lt_max = 50;
RSquare_th = 0.9999;
count = 0;
//loop
While( count < 0.99999, 
//calculate x for each y value
	dt << New Column( "x", Numeric, formula( :y / (:y + :avg_num) ) );
//plot bivariate
	biv = dt << Bivariate(
		Y( :x ),
		X( :average_temp ),
		Fit Line( {Line Color( {212, 73, 88} )} )
	);
	Bivariate_report = biv << report;
	pt = Bivariate_report[Table Box( 1 )];
	pt << Make Combined Data Table();
	pt = Bivariate_report[Table Box( 3 )];
	pt << Make Combined Data Table();
);
//get rsquare
rsquare << Send( Bivariate Fit );
rsquare << Send( Get Gen RSquare Test );
//check Rsq
If(
	rsquare < RSquare_th, 
	//increment light by 1
		lt_min = lt_min + 1,
	count = count + 1, 
	//update data table
		dt << New Column( "light", Numeric, formula( lt_min ) ), 
	//exit loop if RSQ >= threshold
	Print( "Search Completed. RSQ >= threshold" ),
);

The indentation will help understand what code the loop is running. In particular, notice the count=count+1 is not inside the loop, so it will not terminate.

edit: the if statement needs work too, see If Secrets
