Attempting to test Function with Bind Variable --- What am I doing wrong?

Question

When I try to test a function (ComputeFreight) with a bind variable, I get an error, returned.....
"SQL> EXEC :ComputeFreight :=V_ComputeFreight;
BEGIN :ComputeFreight :=V_ComputeFreight; END;
ERROR at line 1:
ORA-06550: line 1, column 25:
PLS-00201: identifier 'V_COMPUTEFREIGHT' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored"
What am I doing wrong?
Below is my code with description ----
create or replace function "ComputeFreight"(p_ORDERNUMBER IN C_ORDER.ORDERNUMBER%TYPE) -- Passing Ordernumber into Function
return NUMBER
is
-- Declaring Variables
v_ComputeFreight NUMBER(10,2);
v_low number (10,2) := 0.05;
v_high number (10,2) := 0.07;
v_SUBTOTAL NUMBER(10,2);
begin
-- Computing order subtotal (Retrieving Item cost and qty from two different tables, multiplying and adding total order cost)
SELECT SUM(O.QUANTITY * I.ITEMPRICE) INTO v_subtotal
FROM ORDER_LINE O JOIN INV_ITEM I
     ON (O.ITEMNUMBER = I.ITEMNUMBER)
WHERE O.ORDERNUMBER = P_ORDERNUMBER;
-- Testing to see which freight charge rate to use
IF
v_subtotal < 300.00 THEN
v_computefreight := v_subtotal * v_low;
ELSE
v_computefreight := v_subtotal * v_high;
END IF;
-- Returning Freight Charge
RETURN v_ComputeFreight;
end "ComputeFreight";

Answer 1

You have made at least 2 errors.
The first one is the name of your function:
create or replace function "ComputeFreight" (You use double quotas and the mixed case in the function name - it means you
make your function name case-sensitive. In the call of your function you have to use double-quoted form "ComputeFreight", nothing else.
If you your function name has to be case-insensitive, don't use double quotas or
use upper-case form: "COMPUTEFREIGHT".
The next mistake is how your call you function. You have to do the following:
var V_ComputeFreight number
EXEC :V_ComputeFreight := <your function name>
V_ComputeFreight is a bind variable and you have to read more about this.
Rgds.
P.S. and as Dave fairly remarked above you have to pass the argument into the function.
