'SSRS expression, IIf statement with three conditions

I have a filter on a Group Properties, CaseNO, that when the three conditions are present to return that row and those three items:

Here is the IIF Statement:

=IIF((Fields!ExtConnID.Value="2") AND (Fields!ExtConnID.Value="200") AND (Fields!ExtConnID.Value="2040"),True,False)

But, I get no hits/data. Can someone with clear eyes and mind, help me out?

Thanks, JER
