Cognos Reporting : Prompt Page

Hi,

I am in the process of creating a prompt page for a Cognos report. I*E task is the data source for the same. I know, one can create a prompt page by simply adding @param to the task

Ex:

@param java.lang.String Number

The above provides a simple text box on the prompt page. Would you be able to tell me how can we have a drop-down or radio box as input on the prompt page ?

The values from the prompt page will be read in the I*E task before the task is fired. The input value will form a part of the where clause for the task.

Thanks,

Malavika
