Enabling / Disabling Cognos Prompt

[j19anna]

Hi Team,

I have two prompt P1 & P2

P1 is multiselect Checkbox prompt and has three values (One need to define default)
P2 is radio button prompt and has only one value.

My requirement is to when P2 is selected. User could not select any value in P1 or it should grey out.

User should not be able to select both the prompt at the same time. Either P1 should Grey out when he select P2.

Or let me know if I could display any error message in the prompt UI when both the prompts are selected.

I know this can be handled with JavaScript. Please do let me know if you have any Idea.

Any solution will work for me.
