making any single prompt as mandatory

Hi All,

I have 3 prompts in a report, I have 3 different prompts by selecting any one (single) prompt the report should run.

-- I have 3 different prompts A, B & C

-- By selecting any one single prompts A or B or C we sholud able to run the report.

How can we achieve this, Thanks in advance.

Thanks,

Neeraj
