PL/SQL :: ORA-06550 - While Compiling Block?

I am trying to resolve by using a cursor C2 inside the already existing cursor C1, i will use a inner loop to get the select statement value to cursor c2 then i will assign the vlaues the variables, then once i read all the values of cursor c2 i will exit inner loop and go to outer loop to read the next value of c1 and then again go to cursor c2 and inner loop.

I have pasted the code below.

Declare
temp1 source.source%type;
temp2 QUOTE_LETTERS_MASTER%rowtype;
Cursor c1 is
Select * from Source;

[code]...
