How to select individual cell based on condition and insert it?

Hello
I am trying to select an individual cell based on condition and insert it to a column in JSL.
For example:

I have this following table - I want to insert to the first row under column "value"  the "score" value of the second row (11) because:
when looking on the first and second row:

home = home and y=y and x=x+1

Input:

score	home	y	x	value
10	US	1	1
11	US	1	2
10	Canada	1	1
10	US	3	5

 

Expected:

 

score	home	y	x	value
10	US	1	1	11
11	US	1	2
12	Canada	1	1
13	US	3	5

 

Thanks

Most likely this isn't exactly what you want, but it does solve your example

Names Default To Here(1);

dt = New Table("Untitled",
 Add Rows(4),
 Compress File When Saved(1),
 New Column("score", Numeric, "Continuous", Format("Best", 12), Set Values([10, 11, 10, 10])),
 New Column("home", Character(16), "Nominal", Set Values({"US", "US", "Canada", "US"})),
 New Column("y", Numeric, "Continuous", Format("Best", 12), Set Values([1, 1, 1, 3])),
 New Column("x", Numeric, "Continuous", Format("Best", 12), Set Values([1, 2, 1, 5])),
 New Column("value", Numeric, "Nominal", Format("", 16), Set Values([., ., ., .]))
);

Row() = 1;
If(:home == Lag(:home, -1) & :y == Lag(:y, -1) & :x + 1 == Lag(:x, - 1),
 :value[Row()] = Lag(:score, - 1)
);
