Your function definitions don't include the arguments x and y that you're calling out on the left hand side.

See attached.

PS: the reason the first loop even worked, was because when you initially defined F(x,y) A[i and B[i were undefined. Therefore whenever you called F(x,y) in the first loop, it would return the variable A[i and B[i. You were defining A, B and i in each iteration of the loop before calling F(A]i, B]i). So the function appeared to work. However, it didn't matter what values you actually passed to the function. You could have called F(10000000, 2342302034) and you still would have returned the present values of A[i + B[i.

When you defined F(x,y) the second time, A, B, and i were already defined. A=[2;4;7], B=[4;12;21] and i=3. Therefore the value of F(x,y) for any x and y was evaluated to 28. (7+21).

Visit these two typical Bolean documents ...
Generally Bolean must be complete [<=, >=].
Otherwise Smath may forgive, but mostly will not forgive.
Among all Bolean, I encountered only one case that <= fails
as the scalar meaning must be vague ... thus <
