INDICATORS IN SSRS ISSUE

Question

Hi,

I am learning the new things in SSRS. Recently I faced an issue regarding Indicators in SSRS. I want to add indicators in my report. The scenario is like this-

I have some documents which states are viz. "APPROVED", "NOT APPROVED", "PENDING".
Now I want to add an indicator on this 3. e.g. If doc is pending then its indicator colour is 'Yellow' and so on. but I was unable to add the conditions. I studied a lots of URL's but I found only the same eg like use Switch and IIF but where I have to use it?

Plz tell me the steps.

Advance Thanks,

Regards,
RAJ
