Javascript Command to call Finish function and Drill through function

[kenrisen]

dear all cognos gurus...

I want create a report that can capture a comment entered by user. I'm doing this using a stored procedure within the database, and using a text prompt within Cognos.

For now user must clik 1 button and 1 drill through :
1. Finish button -> to get comment from text prompt
2. drill through link -> to parse the comment value to the parameter that i created in store procedure
    this drill through link target is it self.

I want create a button or link that can get comment value from text prompt. After that I want that button parse the value to the store procedure parameter.
