Error for wrong number of arguments

Question

Hi
I am getting the below error for plsql
IF (l_src_cd ='P' or l_src_cd = 'E') THEN
ERROR at line 243:
ORA-06550: line 243, column 22:
PLS-00306: wrong number or types of arguments in call to '='
ORA-06550: line 243, column 9:
PL/SQL: Statement ignored
while writing
IF (l_src ='P' or l_src= 'E') THEN
l_activity := 'ERS';
elsif (length(l_adj_cd) > 0) THEN
l_activity := 'KAM';
elsif (length(l_offer_cd) > 0 ) THEN
l_activity := 'RAM';
elsif (length(l_visit_nbr) > 0 ) THEN
l_activity := 'SAM';
ELSE l_activity :='UNK';
END IF;
wrong number or type of argument
Appreciate your help on the above?
Thanks & Regards

What is the data type of l_src?
SQL> declare
  2     type t_tp is table of varchar2(10) index by binary_integer;
  3     l_v t_tp;
  4  begin
  5     l_v(1) := 'A';
  6     l_v(2) := 'B';
  7     if l_v = 'A' or l_v = 'B' then
  8        dbms_output.put_line('True');
  9     else
10        dbms_output.put_line('False');
11     end if;
12* end;
