[Bea2306]

Hi everybody I have had my hp prime for a few weeks now and I have trouble entering this program directly in the calculator. It says that there is a sintaxis problem. Can you help me fix it?Thank you.
This is the programm:
EXPORT PARAL(L1)
BEGIN
LOCAL T;
LOCAL I;
LOCAL N;
T:=0;
I:=0;
N:=SIZE(L1);

FOR I FROM 1 TO N DO
T:=T+1/L1(I);
END;

T:=1/T;
RETURN(T);
END;
