Multiple prompts in one page, issue

[cognosun]

I need 2 separate prompt pages in one page ( 4 parameters in each page), I created a conditional block in prompt page and handled it...each prompt page is linked to one separate report page. Obviously 2 prompt pages has 2 separate names.

Now the issue is...if i open first prompt page and input 2 values and go to second prompt page, it's asking me to input remaining 2 parameter values in first page ?

Strange....

But if i go to one prompt page and input all values and click on finish...it's working fine.

Did anyone faced this situation....please help.
