Function Not Working - Privilege Prob?

[sukimac]

I created a des_encrypt, des_decrypt function as a DBA user, I granted execute rights to the user - they have execute rights on the functions and the package (DBMS_OBFUSCATION_TOOLKIT) but the user gets an invalid column name when he tries to user the function. Both the functions work as the DBA user. Any thoughts would be appreciated.

How does the user call the function?
owner.functionname or functionname?

thank you! When I put the owner schema name in front of the function it worked. I wasn't looking for that b/c I have other functions where I don't have to user owner schema.
