type mis match

[vishnu]

Hi Friends I am new to qtp pleze help me out,
i have created a function lirary and associated it to a test
when i am calling a function in in the test its working properly but when i am calling a function in function library ( the function which is placed in Test )
it was giving a type mismatch error how to solve it...

Ex:
*** test***********

Code:

login
function create(buttion1)
buttion1.click
end function

******in fun lib****************

Code:

Function login
create(obj_buttion)
End function

*************************

That is the code, calling a fun from lib to test is possible or not..
when i try this i was getting a "type mismatch error"
