ASP/OO4O Problem: Unexpect results from package

[CJM]

Repeated for the benefit of m.p.i.asp.general, which I forgot to include in
the original posting...

[Apologies for the premature posting previous to this one]

I'm working on my first Oracle DB, so bear with me...

I have a couple of validation routines which are both returning the same
result regardless of the inputs. One checks if a Serial No already exists,
the other checks if a Part No is valid.

Currently there are no Serial Nos in the system, so this check shouldnt
fail. And I get a response to indicate that the Part No is valid
regardless
of whether it is or not.

I strongly suspect that I'm made the same mistake in each case, but since
I'm not getting any errors, I can't see where.

In both cases, the PL/SQL procedures return a value of 1, whereas if I run
the PL/SQL in SQL Developer with suitable values inserted I get the
expected
results.

[I actually dont know how to output the value of iResult to the screen in
SQL Developer, so I removed the 'INTO iResult' to return a row via the
conventional method- so strictly speaking I'm not testing the exact same
code. Out of interest, how would I run this code and then output the value
of iResult?]

I know the problem will be something silly, but I simply dont know enough
to spot it.

Thanks in advance.
