I think it might be your use of square brackets in the line
s = [|i,1\k-1|]*y[|1\k-1|]
Maybe it should have been
s = s[|i,1\k-1|]*y[|1\k-1|]
or something like that.
Otherwise, I don't think square brackets are allowed to be used to separate elements
of a mathematical expression... use normal brackets instead.
: x = 1,2,3,4
: x
1 2 3 4
+-----------------+
1 | 1 2 3 4 |
+-----------------+
: s = [x:*2]
nothing found where subexp expected
r(3000);
: s = (x:*2)
: s
1 2 3 4
+-----------------+
1 | 2 4 6 8 |
+-----------------+
