Calculating matrix

Hi, this is probably very simple but I can't seem to get Maple to show me the Matrix that I want. Could you please let me know what is the problem?

N₀:=s->1-s;

N₁:=s->s;

N:=s->[N₀(s) N₁(s)];

Both `$`N(s) and N(s) shows me the statement "error, in N[0] too many levels of recursion"

Then I change to N_j:=s->[N₀(s) N₁(s)];

The solution comes out to be [N₀(s) N₁(s)] and not [1-s s]

Question 1: is there any ways that I can name it N(s) without any "j" in it?

Question 2:How do I get N(s) to show me the calculated solution in s values that I insert?

Thanks.
