problem on granting privilige to a function?

Hi All,  

I create a function called get_count(account IN number, claim IN number) under my username test. Then I issued a "grant all on get_count to yliu" (yliu my another username. However, when I log into SQL*PLUS under yliu/passwd, I tried to execute the function "select get_count(84384, 1) from dual", however it told me that get_count is invalid column name. Could someone tell me what the problem is?

Thanks in advance.
