Question: Regarding Active X calls in Forms 5.0

Hi! I'm having some problems today ...This should be simple but... I have an active x control on my form.
I used OLE importer to import its events ect..It just says:

PACKAGE IMAGINELib_CONSTANTS IS
  SUBTYPE z_DIMAGinE IS OleObj;
  SUBTYPE z_DIMAGinEEvents IS OleObj;
  SUBTYPE IMAGinE IS OleObj;
END; All I want to do is set a controls property i.e. DisplayEngine=30;

Display Engine Can return a long which gives the current engine if you don't want to set it..But in this case I want it to be 30.

status:=IMAGinELIB.DisplayEngine(30);

In my package specs I have
FUNCTION DisplayEngine(interface OleObj) RETURN NUMBER;

And in the body I have ...

FUNCTION DisplayEngine(interface OleObj) RETURN NUMBER IS   my_new_value NUMBER;
BEGIN
  Init_OleArgs(0);
  my_new_value := Call_Ole_Num(interface, 49);   return my_new_value;
END; But when I run the form I just get....

FRM-40922: An OLE error occurred: 0X80070057

Question:
1)Do you know what I am doing wrong or how to do it? 2)What does this 0X80070057 mean??
