## Help with Simple DAX formula

I am doing something like this -

PreviousMonth = FORMAT(CALCULATE(MIN(DimDate[Month]), FILTER(DimDate, DimDate[Month_Year] = [SelectedMonthYear]) ), "String")

-  Min(DimDate[Month])  returns a string ... I can see it returns the right string.

But when i now use this calculated "Measure"  (PreviousMonth) - in another formula , the result of that formula returns BLANK ....  When I replace this measure (in that other formula), with a hard coded string , that formula returns the right result !

What am i doing wrong ?

I have tried every kind of thing, it doesn't work !

Try storing the MEASURE value in a variable first

```Revenue =
VAR myMEASURE = [MonthYear]
RETURN
CALCULATE (
SUM ( fact[Revenue] ),
FILTER ( fact, fact[fiscalMonth] = myMEASURE )
)
```

Hi @sqldev2017,

What do you want to use this measure for? what is the context and calculation you arre making on the other measure where this one is used?

## Re: Help with Simple DAX formula

I simply want to return one string value from a table, based on a filter....  That filter will always return one string value (for that table).

I understand CALCULATE is only for numeric measures...

But in this instance CALCULATE also seems to return a string !

Hi @sqldev2017,

Calculate is not only for numeric it can be used in very different ways and the result will be variable text, numbers, etc.

You say in your post that you want to use the measure you calculated in another measure what is exactly your needs? Can you share sample data, setup expected result.

## Re: Help with Simple DAX formula

I am doing something pretty straightforward.

My first "calculated measure"  "MonthYear" returns a value say =  "December 2018"

I use this calculated measure "MonthYear" in a different calculated measure as a Filter parameter -

"Revenue" = CALCULATE(SUM(Revenue), FILTER("fact", fact.fiscalMonth = MonthYear))

I can verify that MonthYear measure actually returns "December 2018"

But Revenue measure returns a blank value.

When I replace the MonthYear parameter , with a hard coded value

"Revenue" = CALCULATE(SUM(Revenue), FILTER("fact", fact.fiscalMonth = "December 2018" )) - Now this returns proper revenue value.

I do not understand why this is happening !  This is just so Bizzare.

## Re: Help with Simple DAX formula

That worked like a Charm.

Thank You.

Honestly,  I was trying to do this FORMAT(Measure, "String")  , that was not working.

This worked.
