Certain features that are available in the database sometimes don't work in Forms (especially your really ancient version). If you can't make it work in a form (by the way, what error did you get when you tried to use it?), you could try to create a stored procedure (or a function). Parameters would be the same that NUMTODSINTERVAL expects; you'd then pass these parameters to NUMTODSINTEVAL and return your own stored function's result to a form. Of course, you have to make sure that NUMTODSINTERVAL works in your database. If not, I'm afraid you are rather helpless (apart from creating your own "numtodsinteval" function).

So as littlefoot said, create your own function covering numtodsinterval one.

variable := mynumtodsinterval (p_n, p_unit);

Is how you would do it in forms 6i and later.
I assume you do the same in forms 2.1 but it's so old I can't be sure.

I really don't understand what your issue is.
Michel has given sample code for the function.
I've shown you how to call it.
What exactly do you not understand?

I have no idea what that means.

If you want to use multiple values you would probably be better off using a procedure.

And what 2 values would you be returning anyway?

That's an example of how to call a function. Variable set equal to function with parameters. If you can't understand that then you need to spend some time reading up on the basics.
I suggest you start with the Database Application Developer's Guide - Fundamentals

The full oracle documentation set can be found here

I also strongly suggest you get rid of forms 2.1 and replace it with something created this century. 10g or 11g forms.
