VBA and lotus notes – Weird Error Message.

I am planning to implement the lotus notes send mail but unfortunately I am facing a weird error message.
Error Message as follows:
The expression On Click you entered as the even property setting produced
The following error: Event procedure declaration does not match description of even having the same name.
* The expression may not result in the name of a macro, the name of a user-defined function, or [Event Procedure].
* There may have been an error evaluating the function, event, or macro.
I shall welcome some help from anyone regarding this issue. My notes client is up and running, I put my password as I was asked to do that. Is it possible to schedule the users to put their password because nearly 130 persons use it, therefore it is not possible to hardcode the password). Lotus Notes 5.0.8 is being used.
