[AccessD] Count query

Hello again,
what about if more then one condition is required ? Like --

SELECT
  Sum(IIf(Not IsNull([Preliminary Investigation Closed]),1,0))as OpenPRE_Inv,
  Sum(IIf(IsNull([Preliminary Investigation Closed]),1,0)) AS Open_Inv,
  Sum(IIf(Not IsNull([First Investigation Document Review]),1,0))AS       
 FirstDocComplete
FROM [Ron Data sprT];

and the condition for the OpenPRE_Inc column should be ([Preliminary
Investigation Closed])not Null and another column [Pre Inv Disposition]not
Null. Same (or actully the opposite) for Open_Inv

is there a way to combine it ? I tried with "and", didn't seenm to work

SELECT
Sum(IIf(IsNull([Preliminary Investigation Closed]),1,0)) AS OpenPRE_Inv,
--(IsNull([Pre Inv Disposition]))
Sum(IIf(Not IsNull([Preliminary Investigation Closed]),1,0)) AS Open_Inv,
--(Not IsNull([Pre Inv Disposition]))
Sum(IIf(Not IsNull([First Investigation Document Review]),1,0)) AS
FirstDocComplete
--( IsNull([Depos Complete]))
FROM [Ron Data sprT];
