Analytics Software

Hello,

Using obiee 11g,
I have a dashboard report where i have one variable prompt now which has 2 values in a list box.
Now i would like to add one more prompt with 2 values such that

if i select value1 from prompt1 then i should get value1 from prompt2 as checkbox.

if i select value2 from prompt1 then i should get value2 from prompt2 as checkbox.

i.e. it should show either value1 from prompt2 or value2 from prompt2 at a time,when i select a value from prompt1,

I hve done something like this when i have column prompts and whne the 2 prompts were depenednt,
but with variable prompts where 2 prompts are just independent of each other,how should i do?

Thanks
