i revice my friend's script,

i got this line in oracle query :

```
select name, contact.utils.occupation_abbr(occupation)
from contact.staff

```

and i got :  

\*"CONTACT"."UTILS"."OCCUPATION\_ABBR": invalid identifier\*

this machine is not the original machine,  

i think i miss copy something from the original machine.  

I see in trigger or function list on the original machine and i don't find this there.

Any suggestion what i left?

== A BIT TRICKY ==

i get the function from packages body,  

then i run the query and make it as function and it now become function :D
