LOV in select box based off of the group the current user is in

Question

Hi,
I need a drop down to display status codes for a user but it that user is a manager then I only need the approval codes to show up. IE: A user will create a record and slect New, Pending Approval, Inprocess and Completed. A manager will see the coes to Approve or Reject. At least that's what I need to happen.
I have been trying to do something like this in a selection list(drop down) in it's LOV section:
DECLARE
VAL BOOLEAN;
BEGIN
VAL := APEX_UTIL.CURRENT_USER_IN_GROUP(p_group_name=>'Managers');
if VAL = true then
select CODE display_value, STATUS_CODE_ID return_value
from STATUS_CODES
where STATUS_CODE_ID in (3, 4)
order by 1;
else
select CODE display_value, STATUS_CODE_ID return_value
from STATUS_CODES
where STATUS_CODE_ID in (1, 2, 5, 6, 7, 8)
order by 1;
end if;
END;
When I run the page it pukes all over itself. Can anyone help me please? Here's the errors:
So for the 1st error, I take it I need a variable to hold each value it's going to return? Is there any easier way to do this? Even if I do change the declarations and add more value holders and change the select statement to stuff the values "into" the variables I declare, how do I return them to the DISPLAY & RETURN values that a LOV expects? IE: get them out of the anonymous block?
ORA-06550: line 1, column 182: PLS-00428: an INTO clause is expected in this SELECT statement ORA-06550: line 1, column 345: PLS-00428: an INTO clause is expected in this SELECT statement.

Thanks for your help in advance!

But, when I run it in toad(im in our apex db), it throws an error.
No, it raises an exception, just as it would in SQL*Plus.
I take it APEX text boxes where you enter code in, are somehow specially parsed?
In most places in Application Express where it lets you enter anonymous blocks, it puts more code around it to be able to use it in the intended context. Sometimes that means treating the code as a boolean function, sometimes it does other stuff. In this case it has to turn the block into a function that returns a SQL query which can then be parsed.
