Passing multiple parameters using FILTER

[Anonymous]

Hi,

I am counting how many times a date from one table appears in another. But I only want to count it if another column is

empty.

DUAL Consent Count = 
CALCULATE ( 
COUNTA ('DUAL Raleigh and Charlotte Combined'[Date Consent SignedV1 Date]),
FILTER ( 
ALL('DUAL Raleigh and Charlotte Combined'[Date Consent SignedV1 Date]), 
'DUAL Raleigh and Charlotte Combined'[Date Consent SignedV1 Date]='DUAL Cumulative Consents'[Date] 
)
)

I have the above that is currently counting everying. I would like it to only be counting the dates if Column X is null. I have tried adding the below but receive an error. 

&& 'DUAL Raleigh and Charlotte Combined'[Column X] <> null

 [Column X] only contains text

Any help would be appreciated!

Hi @Anonymous ,

Have you tried <>"" or create a var that is "" and use that?

Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.
