IF/DAX Statement

Hi bnisbet

it's quite difficult to give you exactly the right statement so replace column names as required. 

There are a couple of options. the easiest (from a readability point of vew) is to break out the two calculate statements and add them together at the end. I'm guessing at some of the column names. 

MyMeasure :=
VAR ProbableVal =
CALCULATE (
Opportunity[EstimatedValue],
Opportunity[Pipeline Reporting Status] = "E",
Opportunity[Status Code] = "Live"
)
VAR ClosedVal =
CALCULATE (
Opportunity[ActualClosedValue],
DATESYTD ( Opportunity[ActualClosedDate], "03/31" ),
Opportunity[Status Code] = "Closed"
)
RETURN
ProbableVal + ClosedVal

it may not be what you are after but it might be of some assistance.
