How to add a procedure from an pl/sql library to an item inside a module

Question

i have created a procedure for example round() function in a plsql library and i saved that library!!!! attached the library into my module and in post_text_item i need to call it
  it shows error, can you please help me out
eg: this is my procedure in plsql library inside forms
PROCEDURE FPROUND(ISAL NUMBER,VSAL OUT NUMBER) IS
BEGIN
  SELECT ROUND(SAL)
  INTO VSAL
  FROM ASIF1;
END;
and now am gonna add this in my block to the item named sal under the trigger post_text_item
declare
isal varchar2(20);
begin
plfuplow(:asif1.sal,isal);
:asif1.sal := isal;
end;
please suggest me with some answers and thanks in advance

Answer 1

my forms version is 10g, actually i have used the procedure name correctly only christian but pasted my code wrongly over here............... and :asif1.sal refers to my block item and the item sal is of datatype(number) only
declare
isal varchar2(20);
begin
FPROUND(:asif1.sal,isal);
:asif1.sal := isal;
end;
my error is:
FRM-92101: there was a failiure in the forms server during startup. this could happen due to invalid configuration.
please look inro thr web-server log file
thanks for your precious comments buddy, hope you guy suggest me a good idea
